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.
What energy changes occur in a microwave oven?
We find that in the microwave oven, electromagnetic energy (microwaves) are converted in thermal (heat) energy.
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.
What forms of energy are in a microwave?
Electrical converted to electromagnetic waves.
When you turn on a toaster what happens to the electrical energy?
The electrical energy gets transformed into electromagnetic (light) energy and thermal (heat) energy.
What energy transformation occurs in an oven?
The electricity (electromagnetic energy) that drives the microwave oven is routed to the magnetron, which generates the microwave energy. (The electricity and microwave energy are both forms of electromagnetic energy.) The microwaves travel through a waveguide into the cavity (the cooking space) in the oven, and used to excite chemical bonds in the food items. This is a conversion of microwave energy (electromagnetic energy) into the mechanical energy of heat.
In a microwave oven electromagnetic energy is changed to what kind of energy?
Heat energy

What are 2 energy conversions that takes place when you warm up a cup of cocoa in a microwave oven?
An energy conversion that takes place when you warm a cup of hot cocoa in a microwave is a transfer of heat from the microwave's microwaves to the hot cocoa.
