Question

this appliance dries clothes primary by converting
heating duct
and element
motor
drum
electrical energy to heat and mechanical energy
mechanical energy to heat and electrical energy
electrical energy to heat and light
mechanical energy to heat and vaporization

Explanation:

A clothes dryer is plugged into an electrical outlet, so it starts with electrical energy. The heating element converts electrical energy to heat (to dry clothes), and the motor (which moves the drum) converts electrical energy to mechanical energy (to rotate the drum). Analyzing the options: The first option says electrical to heat and mechanical, which matches. The second reverses energy sources (dryer doesn't start with mechanical). The third mentions light, which isn't a primary conversion here. The fourth starts with mechanical, which is incorrect.

Answer:

A. electrical energy to heat and mechanical energy
