A rigid tank of volume 0.6 m3 contains saturated R-134a vapor at 24oC. The contents are cooled until the temperature is 0oC. How much heat is removed? Show the process on a P-v diagram.
Approach:
Since the tank is rigid and mass is constant, the specific volume is constant. Find the specific volume at the initial state from property tables and set it equal to the final specific volume. To find heat, use the first law
