Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Refrigerant-134a enters the coils of the evaporator of a refrigeration system as a saturated liquid-vapor mixture at a pressure of 140 kPa. The refrigerant absorbs 175 kJ of heat from the cooled space, which is maintained at -10°C, and leaves as saturated vapor at the same pressure. Determine the entropy change of the refrigerant. Use the tables for...

3. D. Since the pressure of the system finally increases beyond
the initial saturation pressure,
the tank is rigid and the mass of the refrigerant does not change,
what does this imply for the
refrigerant?
A) Finally, the refrigerant is in the saturated vapor
state.
B) Finally, the refrigerant is in the compressed liquid
state.
C) Finally, the refrigerant is in the superheated vapor
state.
D) Finally, the refrigerant maintains the same specific volume but
at a higher pressure.
