Argon is compressed in a polytropic process with n=1.2 from 120 kPa (P1) and 10 °C (T1) to 800 kPa (P2) in a piston-cylinder device.

a) List all the assumptions.

b) Derive the equation of the boundary work (kJ/kg) in terms of P1, T1, & P1. It should include n and R (gas constant). Calculate the boundary work.

c) Calculate the final temperature.

d) Calculate the heat transfer (kJ/kg).

e) Is this a compression or expansion?
