unit 61: engineering thermodynamics
... A compressible fluid (gas or vapour) may be compressed by reducing its volume or expanded by increasing its volume. This may be done inside a cylinder by moving a piston or by allowing the pressure to change as it flows through a system such as a turbine. For ease of understanding, let us consider t ...

Conservation of energy
In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can be neither created nor be destroyed, but it transforms from one form to another, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist. That is to say, no system without an external energy supply can deliver an unlimited amount of energy to its surroundings.
