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 1.6, determine the work and heat transfer, each in kJ per kg of air, (1) assuming constant cy evaluated at 300 K. (2) assuming variable specific heats.
