one mole of a monatomic ideal gas at a temperature of 500k and a pressure of 6atm is experience a complete cyclic reversible process from point a to b to c to d then back to a again.a) the gas is expand isothermally and reversibly to a pressure of 5 atm.b)the gas is expand adiabatically and reversibly untilpressure reaches 4atm and temperature 457k.c) the gas is compressed isothermally and reversibly until the pressure of 4.8atm and 457k.d)the gas is compressed adiabatically and reversibly to a pressure of 6 atm and temperature is 500k.determine volume at each point and construct a pressure versus volume diagram.compute w,q,U and H for each steps and for the whole process.comment on your result.
