Some unknown gas undergoes a polytropic process, pV^1.5 = constant, the initial pressure, p1, is 1 bar, and the initial volume, V1, is 1 m3 . We also know the final volume, V2, is 4 m3 . Please determine 1) the final pressure of the gas, p2, in bar; and the total work done by the gas, W, in kJ; 2) judge the direction of energy flow for the work: into the system or out of the system.
