heat engine
An engine.
A device that converts electric energy into thermal energy. A device that regulates the temperature of a system. A device that uses electric energy to transfer thermal energy from a cooler location to a warmer location. A machine that converts thermal energy into mechanical energy.
Almost every mechanical device converts some of its mechanical energy to thermal energy. Some examples I can think of at the moment are: -- drill bit -- saw blade -- file
mechanical energy
An internal combustion engine is a device that converts chemical energy, typically from fossil fuels like gasoline or diesel, into mechanical energy. This energy is used to power vehicles, machinery, and other mechanical systems.
motor
The device which convert mechanical energy in to electrical energy is "Dynamo".
