a= A Piston-cylinder assembly is initially contains 0.1m3 of ethylene gas at 393K and 35 bar pressure. The pressure of the gas in the piston-cylinder assembly is reversible and iso thermally is being brought to 205 bar. (Inall the options below, thterms of this compression process will be used) a) Assuming that the ethylene obeys the ideal gas equation calculate the heat transferred bet ween the system and its surroundings and calculate the work done. b) Assuming that the ethylen ob ys the Peng-Robinson equation of state. calculate the change in the internal energy during the Process
