Detailed explanation-1: -Hair dryers use the motor-driven fan and the heating element to transform electric energy into convective heat.

Detailed explanation-2: -Electric heating is any process in which electrical energy is converted to heat. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical appliance that converts electrical energy into heat.

Detailed explanation-3: -The energy into the hairdryer includes the electric work, the total enthalpy of the incoming air, and the kinetic energy of the incoming air. Energy out of the hairdryer includes the total enthalpy of the outgoing air, kinetic energy of the outgoing air, and any heat transfer from the case to the ambient.
