Question

Household appliances convert electricity into one or more different forms of energy. An electric fan can best be described as converting electricity into:

a Heat energy only.
b Heat energy and sound energy only.
c Heat energy, sound energy, and mechanical energy only.
d Heat energy, sound energy, mechanical energy, and chemical energy

Answer 1

An electric fan converts electricity into heat energy, sound energy, and mechanical energy.

Step-by-step explanation:

An electric fan can best be described as converting electricity into heat energy, sound energy, and mechanical energy. When electricity is supplied to the fan, the fan motor converts electrical energy into mechanical energy, causing the blades to rotate and move air. This movement of air creates sound energy and friction, which produces heat energy.
