Question
An engine goes through the reversible cycle shown. The engine contains n = 8 mol of a diatomic ideal gas with specific heat at constant volume of 20.8 J/(K mol). The process 3 -> 1 is an isothermal process (recall the work done during such a process is nRT ln(Vi/Vf)). The other two process types can be inferred from the diagram. At point 3, the pressure of the gas is 12 105 Pa, its temperature is 1530 degrees celsius, and its volume is 0.1 m3. At point 2, the temperature of the gas is 30 degrees celsius.
