A piston-cylinder assembly contains Ammonia initially at a pressure p = 500 kPa and specific volume v = 0.24533 m^3/kg (state 1). Expansion occurs to a state where the pressure is 150 kPa (state 2). During the process the pressure and specific volume are related by pv=constant. For the Ammonia, determine the work and heat transfer per unit mass, each in kJ/kg
