Problem 3: A closed, rigid tank whole volume is 1.5m3 contains Refrigerant 134 a, initially a two-phase liquidvapor mixture at 10C. The refrigerant is heated to a final state where temperature is 50C and quality is 100%. Locate the initial and final states on a sketch of the T-v diagram. Determine the mass of vapor present at the initial and final states, in kg
