A microwave oven incorporates a microwave generator which produces EM energy at the right wavelength or frequency to energise water molecules in the food being cooked, which produces thermal energy in the food. The microwaves don't escape from the oven because they don't penetrate the materials the enclosure is made from. (EM = electromagnetic)

What type of energy does a microwave oven give off?
radiation
What energy do all objects give off?
All objects give off thermal radiation.
Do all objects give off thermal radiation?
yes every object gives out thermal radiation
What do all objects give off?
All objects give off thermal radiation.
What type of energy does steam give?
Thermal energy (heat) and Kinetic energy (movement).
What type of energy does a microwave oven give off?
radiation
What energy do all objects give off?
All objects give off thermal radiation.
Does the transfer of thermal energy by radiation require matter?
Now, this question has two answers. To give rise to, and to absorb, thermal radiation, matter is needed. Energy in the form of gravitational or electromagnetic fields neither emits nor absorbs thermal radiation. However, thermal radiation, an electromagnetic wave, does not need matter to transverse space.
Do all objects give off thermal radiation?
yes every object gives out thermal radiation
What do all objects give off?
All objects give off thermal radiation.
How does a star give light?
The fusion of hydrogen into helium provides energy, which is partially converted into heat, which produces light according to the black body thermal radiation equation.
What are the example of technology that give bad effects?
mobile phones giving out microwave radiation.
What type of energy does steam give?
Thermal energy (heat) and Kinetic energy (movement).
What 2 forms of energy does fire give out?
Obviously its Thermal and Chemical Energy
Give an example of thermal energy?
When you rub two things together, like your hands, thermal energy is produced. This is a result of the friction.
Can you give me at least 10 appliances that uses thermal energy with picture?
Stove Refrigerator Microwave Iron Curling Iron Blow dryer Furnace Hot water heater Toaster Coffee Pot
Give an example of one type of energy conversion change to another form?
Heating food in a microwave: Electromagnetic radiation energy in the form of microwaves cause increased vibration of bonds in water molecules resulting in the increased heat production.
