A two-phase liquid–vapor mixture of Refrigerant 134a is contained in a 2-ft3, cylindrical storage tank at 100 lbf/in.2 Initially, saturated liquid occupies 1.6 ft3. The valve at the top of the tank develops a leak, allowing saturated vapor to escape slowly. Eventually, the volume of the liquid drops to 0.6 ft3. If the pressure in the tank remains constant, determine (a) the mass of refrigerant that has escaped, in lb, and (b) the heat transfer, in Btu. PLEASE USE THE...

One kilogram of Refrigerant 134a vapor initially at 2 bar and 20°C fills a rigid vessel. The vapor is cooled until the temperature becomes -24°C. There is no work during the process. Let To = 20°C, po = 0.1 MPa and ignore the effects of motion and gravity. 2. For the refrigerant, determine the change in exergy, in kJ. Note: for part 1: q=-98.086kj please find part two- the change in exergy in kj
