A rigid container with a volume of 2 m3 contains twenty kilograms of refrigerant 134a at an initial pressure of 240 kPa. The container is cooled until the pressure of the refrigerant is 100 kPa. Determine: a) The initial temperature of the refrigerant; (5 marks) b) The final state (i.e., compressed liquid, saturated liquid, saturated mixture etc.) of the refrigerant, giving your reasoning; and (3 marks) c) The heat transfer associated with the process.
