1.Refrigerant-134a is to be compressed from 0.14 MPa and 10°C to 0.8 MPa and 50°C steadily by a compressor. Taking the environment conditions to be 20°C and 95 kPa, determine the exergy change of the refrigera during this process and the minimum work input that needs to be supplied to the compressor per unit mass of the refrigerant.
