A) electrical to chemical.
Eliminate
B) electrical to mechanical.
C) mechanical to electrical.
D) chemical to electrical.

Answer 1

Hello,

The answer is B) electrical to mechanical.

When a hair dryer is being used, one of the energy transformations that takes place is electrical to mechanical. Once you plug the hair dryer into the outlet, an electric current flows, starting the mechanical hair dryer.

Answer 2

When a hair dryer is being used, one of the energy transformations that takes place is electrical to mechanical.

The hair dryer uses electric motor which converts the alternating current supplied to the dryer into mechanical energy of the moving parts of the dryer.

Some of electrical energy may be lost to friction in the moving parts of the dryer. This leads to another energy conversion from mechanical energy into heat energy.

Thus, we can conclude that when a hair dryer is being used, one of the energy transformations that takes place is electrical to mechanical.
