What kind of energy does a microwave oven use?
A microwave oven uses electrical energy (which is electromagnetic energy) from the mains, and it generates microwave energy (which is also electromagnetic energy) to heat/cook food items.
How is the electromagnetic energy from the microwave transformed into heat energy?
It is absorbed by the food.
What are Energy transformations in a microwave?
The microwave undergoes a variety of energy transformations when you are heating food. Starting from electrical energy (obtained via the mains power point/wall socket), the energy is transformed into microwave/thermal radiation (electromagnetic radiation/energy). These 'microwaves' react with the water particles in the food and cause them to vibrate. The friction produced by these vibrations produces heat and ultimately cooks/heats up your food. However, there is some energy that is transformed into light (the light you see when the microwave is one), sound (that humming noise you hear when it's operating) and kinetic energy (the rotating disk inside the microwave). Energy is transformed from electrical to heat, sound and light (if the microwave has a light). Energy is transferred to the food via the process of convection.
How is kinetic energy used in a microwave oven?
Kinetic energy is the mechanical energy (thermal energy) that does the heating/cooking in a microwave oven. The microwaves that the oven generates stimulate chemical bonds in food, and this is the conversion of electromagnetic energy into that heat we mentioned.
What is the energy transformation of a microwave?
It transforms electrical input energy into microwave EM radiation, this radiation then agitates water molecules in food to raise the temperature.

What is the energy conversion for microwave?
The type of energy conversion for a microwave is the transformation of electrical energy into light energy. This device works by focusing microwave light on the food inside of it.
How is the microwave used in heating?
it generates energy from light and heat. Which causes food to have moisture in it. It makes food cook faster or defrost faster.
How is the electromagnetic energy from the microwave transformed into heat energy?
It is absorbed by the food.
Does microwave radiation carry a lot of energy?
It can do certainly. In a microwave oven there is enough energy to heat food quickly
Why do Microwave Ovens interfere with Satellite T V?
A microwave oven would interfere with you satellite TV do to the energy grenerated by the (klystron?) tube that generates the energy to cook the food. Howevr, that said, a your microwave should NOT interfere with your TV If it does, I would have the seals checked on your microwave, and would not stand near it when it is running.
When you cook food in a microwave oven why doesn't the plate get get cooked?
Plates are usually either ceramic or glass. Both materials are transparent to the microwave radiation in a microwave oven. The electromagnetic energy goes right through the plates like they weren't there. It is the food that heats the plate as that food is being heated. Remember that the microwave radiation is "tuned" to work on the hydrogen-oxygen bonds in water. It gives them "energy" and heats them up. There are some plates that will actually get a bit hot directly from the microwave energy, but that depends on the composition of the plate.

Why does a microwave oven turntable rotate in either direction?
The turntable in a microwave oven is driven by an alternating current motor which may start in either direction at random and continues to travel in that direction until stopping. The reason for using a turntable in a microwave oven is that the microwave energy is not evenly distributed across the oven. The turntable allows the food to receive an equal amount of energy by turning across the uneven microwave field. The microwave energy is turned to heat within the food. It actually does not matter in which direction the turntable rotates in order to evenly cook the food.
