One mole of ideal gas, initially at 50OC and 1 bar, is changed to 150oC and 4bar by 2 different mechanically reversible processes as follows:
process 1: the gas is first heated at constant pressure until its temperature is 150oC and then it is compressed isothermally to 4 bar
process 2:the gas is first compressed adiabatically to 4bar and then it is cooled at constant pressure to 150OC
i)Assume Cv =2.5R and Cp=3.5R, estimate the heat(J) and work(J) for both processes
ii)Select the most energy efficient process.Justify your answer.
