Which of the following statements about the reversible polytropic process of an ideal gas is correct? (1) A process that satisfies pV1^m = pV2^m. (2) A process in which there is no heat exchange between the system and the surroundings. (3) A process in which pV^m remains constant at all points. (4) An isentropic process. The answer is (3). Why is that? Thank you
BD is a reversible adiabatic process, whereas the definition of a reversible polytropic process is PVn = constant. Every arbitrary process must be a constant
