2. Carnot Engine A uses 1mol monatomic ideal gas as working medium. The temperature for isothermal expansion is 4T0. The temperature for isothermal compression is T0. The starting volume for the isothermal expansion is V0. The starting volume for the isothermal compression is 64V0. (See the figure below.) For each Carnot circle, Engine A exerts work WA to the surroundings. Carnot Engine B undergoes the same circle as Engine A. However, it uses diatomic ideal gas as working medium. It exerts work WB every circle. (1) Find the ratio: WB/WA. First give your result as a function of =Cp/Cv, then calculate the numerical value of WB/WA using the values of for monoatomic and diatomic molecules
