(a) 1 mole of an ideal gas is allowed to expand against a piston supporting 0.041 MPa, the temperature being constant at 0 °C (273.15 K). The initial pressure is 1.01325 MPa and the final pressure is 0.041 MPa. Calculate W, Q. AU and AH. b) If the change is made in such a way that the confining pressure is at all times lower than the gas pressure, find the value of W, Q, AU and AH.
