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.

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. T…
