Question

multiple - choice question
a toaster transforms
electrical energy into heat energy
heat energy into electrical energy
light energy into chemical energy
chemical energy into light energy

Explanation:

A toaster is an electrical appliance. It uses electrical energy. When it operates, it generates heat to toast bread. So it transforms electrical energy into heat energy. The other options are incorrect as a toaster has no mechanism to transform heat into electrical (it consumes electricity, doesn't produce it), light into chemical (no such process in a toaster), or chemical into light (again, not relevant to a toaster's function).

Answer:

electrical energy into heat energy
