Question: Problem 3 ( 1 5 points ) : Air is expanded from 3 0 0 kPa, 5 0 0 K to 1 5 0 kPa

Problem 3(15 points): Air is expanded from 300kPa,500K to 150 kPa in a piston/cylinder in a reversible adiabatic process. The specific heat is assumed to be constant. Find the final temperature T2, the work done by the air and the expansion ratio V2V1(the ratio of final specific volume to initial specific volume).
