Air undergoes a polytropic process in a piston–cylinder assembly from p1 = 1 bar, t1 = 295 k to p2 = 9 bar. the air is modeled as an ideal gas and kinetic and potential energy effects are negligible. for a polytropic exponent of 1.4, determine the work and heat transfer, each in kj per kg of air, (1) assuming constant cv evaluated at 300 k. (2) assuming variable specific heats.
