A piston-cylinder device holds 2 kg of refrigerant fluid R-134a, initially at 500 KPa. At this state, 0.5 kg of the fluid is in the liquid phase. Heat is then added to the fluid at constant pressure to increase its temperature to 60 c. Calculate the.
A) Change in volume during the process ( in m^3)
B) Amount of heat added during the process ( in kJ)
