It got stuck when depressed, and even though it would unstick, it was clearly defective. At the end of each cycle, there is a four-beep alarm, and then there is a one-beep alarm every minute thereafter. Sometimes keeping your finger on the release for a long period of time before it opens, other times you just have to push hard and often. The release button just doesn’t work well or consistently on my new microwave. I am ready to return the thing, which by the way works fine as a microwave oven.First one came with our brand new house but went wonky within the one year warranty.

I have memorized a tray of bacon at 6 minutes, presto, push just the “6” & good to go. So be aware if it fails you’re going to be in for a long and annoying warranty process. Within two months of purchase, the door button quit functioning. Probably the most important feature of this unit is that the radiation leakage around the door is practically zero. Sometimes you have to push the “release” (or open button) five or six times before it opens, sometimes just one time will work (it’s much, much more the former).

Sometimes you have to use two hands, with one hand actually opening the door as you push with the other. I thought at first this was going to be just a minor annoyance but not anymore. Just because it needs to be smaller doesn’t mean we want to give up options!

A bowl of cut up potatoes covered, also 6 minutes, stir, & check if done. Getting a replacement under warranty but it looks like the process will leave me without a microwave for 1-2 weeks.

Methods Of Heat Transfer by physicsclassroom.com

You have hopefully adopted an understanding of heat as a flow of energy from a higher temperature object to a lower temperature object. The heat transfer continues until the two objects have reached thermal equilibrium and are at the same temperature. How does heat transfer work within the bulk of an object?

In this instance, the transfer of heat from the hot water through the metal can to the cold water is sometimes referred to as conduction. Only energy is transferred from the hot water to the cold water.

And other than the gain of energy, there is nothing else entering the cold water. These particles are in constant motion; this gives them kinetic energy. This is known as translational kinetic energy and is the main form of kinetic energy for gases and liquids. This gives the particles vibrational kinetic energy and is the main form of kinetic energy for solids. The wigglers are those particles vibrating about a fixed position. The bangers are those particles that move through the container with translational kinetic energy and collide with the container walls. Just as the perimeter of your property (as in real estate property) is the furthest extension of the property, so the perimeter of an object is the furthest extension of the particles within a sample of matter. Even the wigglers that are fixed in a position along the perimeter are doing some banging. At this perimeter or boundary, the collisions of the little bangers and wigglers are elastic collisions in which the total amount of kinetic energy of all colliding particles is conserved. The more energetic particles will lose a little kinetic energy and the less energetic particles will gain a little kinetic energy. So on average, there are more particles in the higher temperature object with greater kinetic energy than there are in the lower temperature object. The collisions of our little bangers and wigglers will continue to transfer energy until the temperatures of the two objects are identical. At thermal equilibrium, there are an equal number of collisions resulting in an energy gain as there are collisions resulting in an energy loss.

At the macroscopic level, heat is the transfer of energy from the high temperature object to the low temperature object. Being a fluid, those particles move about with translational kinetic energy and bang upon the particles of the metal can. The can assumes nearly the same temperature as the hot water. The collisions between the particles of the metal can and the particles of the cold water result in the transfer of energy to the cold water. The interaction between the particles of the hot water, the metal can and the cold water results in a transfer of energy outward from the hot water to the cold water. At the macroscopic level, one would observe a decrease in temperature of the hot water and an increase in temperature of the cold water. In conduction, there is no net transfer of physical stuff between the objects. The changes in temperature are wholly explained as the result of the gains and losses of kinetic energy during collisions. But how does it transfer through the bulk of an object?

Energy first flows into the particles at the boundary between the hot coffee and the ceramic mug. How does heat conduction occur in the ceramic itself?



Granite Countertops Is Radon And Radiation A Real Concern? | Duration 3 Minutes 6 Seconds

As the ceramic particles at the boundary between the hot coffee and the mug warm up, they attain a kinetic energy that is much higher than their neighbors. These particles in turn begin to wiggle more vigorously and their collisions with their neighbors increase their vibrational kinetic energy. This mechanism of conduction by particle-to-particle interaction is very common in ceramic materials such as a coffee mug. The burners on the stove transfer heat to the metal skillet. The transfer of heat from the skillet to the skillet handle occurs by conduction. In a manner similar to electrical conductivity, thermal conductivity in metals occurs by the movement of free electrons. The details of this mechanism of thermal conduction in metals are considerably more complex than the discussion given here. This qualifies the heat transfer as being categorized as thermal conduction.

The ceramic of the coffee mug and the metal of the skillet are both solids. Liquids and gases are fluids; their particles are not fixed in place; they move about the bulk of the sample of matter. Convection is the process of heat transfer from one location to the next by the movement of fluids. The fluid flows from a high temperature location to a low temperature location. As the metal becomes hot, it begins to conduct heat to the water. Differences in water density between the bottom of the pot and the top of the pot results in the gradual formation of circulation currents. As the hot air rises, it pushes some of the cold air near the top of the room out of the way. As the colder air approaches the heater at the bottom of the room, it becomes warmed by the heater and begins to rise. As the more energetic particles of the heated air mix with the cooler air near the ceiling, the average kinetic energy of the air near the top of the room increases. The net result of the rising hot fluid is the transfer of heat from one location to another location. This is not to be confused with the caloric theory discussed earlier in this lesson.Our model of convection considers heat to be energy transfer that is simply the result of the movement of more energetic particles. In contrast to natural convection, forced convection involves fluid being forced from one location to another by fans, pumps and other devices. Air is heated at a furnace and blown by fans through ductwork and released into rooms at vent locations. The movement of the fluid from the hot location (near the furnace) to the cool location (the rooms throughout the house) is driven or forced by a fan. Some fireplaces enhance the heating ability of the fire by blowing heated air from the fireplace unit into the adjacent room. The energy is carried by electromagnetic waves and does not involve the movement or the interaction of matter.



The Truth About Granite, Radon, And Radiation | Duration 8 Minutes 16 Seconds

The sun obviously radiates off more energy than a hot mug of coffee. Objects at typical room temperatures radiate energy as infrared waves. The energy radiated from an object is usually a collection or range of wavelengths. Hotter objects tend to emit shorter wavelength, higher frequency radiation. Fortunately, this provides a convenient warning to its users that the coils are hot. This radiation not only allows us to see, it also warms the glass bulb that contains the filament. Thermal radiation is a form of heat transfer because the electromagnetic radiation emitted from the source carries energy away from the source to surrounding (or distant) objects. In this sense, energy is transferred from one location to another by means of electromagnetic radiation. The camera detects the radiation emitted by objects and represents it by means of a color photograph. On the next page, we will investigate the mathematics associated with the rate of heat transfer. Do the particles of the two objects still collide with each other?

The fact that the temperature is identical means that the average kinetic energy of all the particles is the same for both objects. When the effect of these collisions is averaged , there is no net energy transfer.

You should be developing a model of matter as consisting of particles which vibrate (wiggle about a fixed position), translate (move from one location to another) and even rotate (revolve about an imaginary axis). The more the particles vibrate, translate and rotate, the greater the temperature of the object. It is the temperature difference between the two neighboring objects that causes this heat transfer. The discussion of heat transfer has been structured around some everyday examples such as the cooling of a hot mug of coffee and the warming of a cold can of pop. Why is thermal equilibrium always established when two objects transfer heat?

Heat is transferred from the hot water to the cold water until both samples have the same temperature. There is nothing physical or material moving from the hot water to the cold water. Other than the loss of energy, there is nothing else escaping from the hot water. To understand the answer, we have to think about matter as consisting of tiny particles atoms, molecules and ions. As mentioned previously in this lesson, these particles move throughout the space of a container, colliding with each other and with the walls of their container. But these particles can also vibrate about a fixed position. To put it more simply, matter consists of little wigglers and little bangers. The container walls represent the perimeters of a sample of matter. At the perimeter, the little bangers are colliding with particles of another substance – the particles of the container or even the surrounding air. Being at the perimeter, their wiggling results in collisions with the particles that are next to them; these are the particles of the container or of the surrounding air. The net effect of these elastic collisions is that there is a transfer of kinetic energy across the boundary to the particles on the opposite side. Temperature is a measure of the average amount of kinetic energy possessed by the particles in a sample of matter. So when we average all the collisions together and apply the principles associated with elastic collisions to the particles within a sample of matter, it is logical to conclude that the higher temperature object will lose some kinetic energy and the lower temperature object will gain some kinetic energy. When this state of thermal equilibrium has been reached, the average kinetic energy of both objects’ particles is equal.

On average, there is no net energy transfer resulting from the collisions of particles at the perimeter. On average, the particles with the greatest kinetic energy are the particles of the hot water. As the hot water particles bang upon the particles of the metal can, they transfer energy to the metal can. Most metals are good thermal conductors so they warm up quite quickly throughout the bulk of the can. The average kinetic energy of the hot water particles gradually decreases; the average kinetic energy of the cold-water particles gradually increases; and eventually, thermal equilibrium would be reached at the point that the particles of the hot water and the cold water have the same average kinetic energy. The mechanism in which heat is transferred from one object to another object through particle collisions is known as conduction. But then it flows through the bulk of the ceramic to all parts of the ceramic mug. The mechanism of heat transfer through the bulk of the ceramic mug is described in a similar manner as it before. As they wiggle more vigorously, they bang into their neighbors and increase their vibrational kinetic energy. The process of energy transfer by means of the little bangers continues from the particles at the inside of the mug (in contact with the coffee particles) to the outside of the mug (in contact with the surrounding air). If the handle of the skillet is metallic, it too attains a high temperature, certainly high enough to cause a bad burn. But in metals, the conduction mechanism is slightly more complicated. These electrons carry the energy from the skillet to the skillet handle. The main point to grasp is that heat transfer through metals occurs without any movement of atoms from the skillet to the skillet handle. The model of heat transfer through the ceramic coffee mug and the metal skillet involved conduction. Heat typically does not flow through liquids and gases by means of conduction. The model used for explaining heat transfer through the bulk of liquids and gases involves convection. To understand convection in fluids, let’s consider the heat transfer through the water that is being heated in a pot on a stove. The metal pot that holds the water is heated by the stove burner. So as the water at the bottom of the pot becomes hot, its density decreases. And the colder water that was present at the top of the pot moves towards the bottom of the pot where it is heated and begins to rise. Convection also explains how an electric heater placed on the floor of a cold room warms up the air in the room. As the air warms up, it expands, becomes less dense and begins to rise. The cold air moves towards the bottom of the room to replace the hot air that has risen. Convection is the main method of heat transfer in fluids such as water and air. The more appropriate explanation is to say that heated fluid rises. This increase in the average kinetic energy corresponds to an increase in temperature. The convection method of heat transfer always involves the transfer of heat by the movement of matter. In caloric theory, heat was the fluid and the fluid that moved was the heat. The two examples of convection discussed here – heating water in a pot and heating air in a room – are examples of natural convection. The earth’s oceans and atmosphere are heated by natural convection. Some ovens are forced convection ovens; they have fans that blow heated air from a heat source into the oven. Radiation is the transfer of heat by means of electromagnetic waves. The transfer of heat by radiation involves the carrying of energy from an origin to the space surrounding it. All objects radiate energy in the form of electromagnetic waves. The temperature also affects the wavelength and frequency of the radiated waves. Being invisible to the human eye, we do not see this form of radiation. The coils of an electric toaster are considerably hotter than room temperature and emit electromagnetic radiation in the visible spectrum.

The tungsten filament of an incandescent light bulb emits electromagnetic radiation in the visible (and beyond) range. Put your hand near the bulb (without touching it) and you will feel the radiation from the bulb as well. This energy is absorbed by those objects, causing the average kinetic energy of their particles to increase and causing the temperatures to rise. The image at the right was taken by a thermal imaging camera. The hotter colors represent areas of objects that are emitting thermal radiation at a more intense rate. Conduction, convection and radiation have been described and illustrated. The two objects are placed next to each other and the little bangers begin colliding. But there is a range of speeds and thus of kinetic energy in both objects. Just because the temperatures are the same doesn’t mean the collisions will stop. This explains why the temperature of the two objects remains the same.

Why We Don’t Use A Microwave by wellnessmama.com

In my opinion, food cooked or reheated in the microwave does not taste as good!

That’s why microwave ovens on the market must operate at or below strict limits set by the federal government. That is, since water molecules are polar, having a positive end and negative end, they begin to rotate rapidly as the alternating electric field passes through. By their nature, they do release radiation in to food, but the disagreement regards whether the radiation is released outside of the microwave itself. However, occasional home use of a fully functional microwave appliance is generally considered safe. And, of course, it’s a good idea to replace an old, dilapidated microwave even if it’s a great conversation piece. There is evidence that heating certain materials (like plastic) in the microwave can cause harm. Any cooking will actually change the nutrients in food in some way, though low and slow cooking seems to preserve the most nutrients while faster methods of cooking (microwave being the fastest) destroy more nutrients. By comparison, steamed broccoli lost 11% or fewer of its antioxidants.This kind of breakdown took about 25 minutes of boiling with conventional heat. Microwaves don’t produce the best tasting food, they might destroy nutrients, and there is a possibility that they might releaser harmful radiation. Obviously, most people aren’t willing to give up the convenience of a microwave, so at least avoid using plastic in it!

This supposedly combines the quick cooking of a microwave with the safety and quality of the oven). Still, microwaves can obviously cause heating effects, and can harm or kill at high energies. Common sense adds that you might want to make sure the microwave seal isn’t compromised by built up tomato sauce or other grime. From a radiation perspective, the general consensus seems to be that microwaves could transmit radiation, though it is unlikely.Mercola gives some compelling evidence of this possibility though. There were also reductions in phenolic compounds and glucosinolates, but mineral levels remained intact (6). For me, this was an easy choice- if it might be harmful and doesn’t make good tasting food, we avoid it. Breakfast omelets are cooked on the stove, leftovers heated for lunch and veggies steamed for dinner.
