A Carnot engine has 40 g of helium gas as its working substance. It operates between two reservoirs of temperatures T1 = 400°C and T2 = 60°C. The initial volume of the gas is V1 = 2.0 X 10-2 m3, the volume after isothermal expansion is V2 = 4.0 X 10-2 m3, and the volume after the subsequent adiabatic expansion is V3 = 5.0 X 10-2 m3.
(a) Calculate the work generated by this engine during one cycle. (book answer = 2 x 10^4 J)
(b) Calculate the heat absorbed and the waste heat ejected during one cycle. (book answer = absorbed 3.9x 10^4 J and ejected 1.9 x 10^4 J)
