Heat engines like your lawn mover or car a combustion engine.
A bi-metallic strip
heat engine
steam engine
An engine.
The motor changes electrical energy into mechanical (torque) energy.
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.
Steam engine is a device that transforms thermal energy into mechanical energy. An internal combustion engine (I.C Engine) can transform thermal energy into mechanical energy. In nuclear power plant also the heat energy released is used to turn the turbine and thus thermal energy is converted into mechanical energy of rotation of turbine. This mechanical energy of turbine is further converted into electrical energy in generator.
A steam engine.
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
An electrical generator
a device that changes mechanical energy into electrical energy
An electric motor is the best for that job.
