A refrigerant 134a is compressed reversibly in a cylinder according to a polytropic law from 0.8 bar, dry saturated, to 2.2 bar when the temperature is then 40 degrees Celsius. Using refrigerant table, determine (a) the specific volumes and polytropic index, (b) the work input compression process, and (c) the specific internal energies of each state and heat transferred to or from the cylinder walls during the process.
