WebThis formula only requires that Psys(V) and T are well defined, that is, a system of uniform P and T (“uPT”) undergoing a “uPT process”, which may be irreversible. An instructive example is an expanding gas accelerating a bullet horizontally and performing work without a conventional external pressure.

Heat engines use a complete cycle of thermodynamic processes to convert heat energy into mechanical energy, usually by moving a piston as the gas in the heat engine expands. Isothermal processes are a key part of this cycle, with the added heat energy being completely converted into work without any loss.
