What energy transformation occurs in an oven?

Answer 1

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.

Answer 2

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.

Answer 3

Electrical energy is transformed into heat energy.

Answer 4

Microwaves use Radiation, as oposed to Convection using hot Air or Conduction to be cooked in a liquid such as boiling.

Answer 5

heat energy
