Steam Engine
A steam engine is a heat-powered engine that performs mechanical work by containing steam. Steam engines use the pressure of the steam to push a piston back and forth inside a cylinder. This forward motion can be converted with a crank and connecting rod into a rotational one. The term "steam engine" is most accurately used to refer to reciprocating engines as just described, but steam turbines are also called by that name occasionally.
