Air undergoes a polytropic process in a piston-cylinder assembly from p₁ = 1 bar, T₁ = 295 Kto p2 = 7 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 c evaluated at 300 K. (2) assuming variable specific heats.
