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 else can I help you with?
What energy do all objects give off?
All objects give off thermal energy, also known as heat, in the form of infrared radiation. Thermal energy is a result of the motion of the atoms and molecules that make up the object.
What do all objects give off?
All objects give off thermal radiation.
What type of energy does a microwave oven give off?
A microwave oven gives off electromagnetic radiation in the form of microwaves. These microwaves are used to heat and cook food quickly and efficiently.
Do all objects give off thermal radiation?
yes every object gives out thermal radiation
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.
What energy do all objects give off?

What 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.
What type of energy does a microwave oven give off?

Do all objects give off thermal radiation?
yes every object gives out thermal radiation
Does the earth give off radiation?
Yes, the Earth does give off radiation in the form of heat. This radiation is primarily in the form of thermal infrared radiation emitted by the Earth's surface in response to solar energy absorbed during the day.
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.
Why do animals and people give off electromagnetic radiation?
Animals and people give off electromagnetic radiation as heat energy through a process called thermal radiation. This is a natural byproduct of metabolic processes that occur within living organisms. The electromagnetic radiation emitted is in the form of infrared light, which is invisible to the human eye but can be detected with thermal imaging technology.
What type of energy does any object above absolute zero give off?
Any object above absolute zero gives off thermal energy in the form of heat radiation.
What are the example of technology that give bad effects?
mobile phones giving out microwave 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.
Does everything not at the temperature zero give off radiation?
Yes, everything above absolute zero emits thermal radiation. This radiation is emitted as electromagnetic waves due to the thermal motion of the particles within the object.
