A Carnot engine has 40 gram of Helium gas as its working substance. It operates between two reservoirs of temperatures T1= 400 Celsius and T2= 60 Celsius. The initial volume of the gas is V1= 2e-2 m3 and the volume after isothermal expansion is V2= 4e-2 m3 and the volume after the subsequent adiabatic expansion is V3=5e-2 m3.
a) Compute the work generated by this engine during one cycle.
b) Find the heat absorbed and the waste heat ejected during one cycle.
