Fundamentally, there are two energy conversions taking place: electrical energy is converted into heat energy in the heating coils and electrical energy is converted into mechanical energy in the fan motor. The moving air transfers heat to wet hair by convection, so the temperature of the water rises, which causes its evaporation rate to increase. Some of the heat is absorbed by the water molecules as they go from the liquid phase to the vapor phase.
Secondarily, some of the heat is emitted as infrared radiation and some of the mechanical energy is emitted as sound waves. Eventually, these all dissipate as heat within the room.
When sunlight strikes a house, the energy transformation that takes place is from radiant energy (sunlight) to thermal energy (heat). The house absorbs the sunlight, which then gets converted into heat energy, warming up the interior.
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
In the engine of a typical train, the energy transformation that takes place involves converting the chemical energy stored in fuel (such as diesel) into mechanical energy through combustion. This mechanical energy is then used to move the train by powering the wheels.
Mechanical energy from the fan motor is converted into thermal energy (heat) by the heating element in the hair dryer.
When a lawn mower is used, the energy transformation that takes place is from chemical energy stored in the fuel (such as gasoline) being converted into mechanical energy that powers the movement of the mower blades. The mechanical energy is then used to cut the grass and do the work of mowing the lawn.
