Isentropic compression describes an idealised thermodynamic process in which a gas is compressed in such a way that its entropy remains constant. In other words, the process is reversible and adiabatic, with no entropy generated by irreversibilities such as friction, turbulence, or heat transfer to surroundings. Although real systems never achieve perfect isentropic conditions, the…
