An insulated spring-loaded piston/cylinder is connected to an air line flowing air at 600 kPa, 700 K by a valve. Initially the cylinder is empty and the spring force is zero. The valve is then opened until the cylinder pressure reaches 300 kPa. By noting that u2 uline CV (T2 Tline) and hline uline RTline find an expression for T2 as a function of P2, Po Tline. With P 100 kPa, find T2.
