For an ideal gas with initial pressure and volume \(P_{i}\) and \(V_{i}\), respectively, a reversible isothermal expansion happens, when its volume becomes \(V_{0}\). Then it is compressed to its original volume \(V_{i}\) by a reversible adiabatic process. If the final pressure is \(P_{f}\), then which of the following statements is true?

One mole of a mono-atomic ideal gas undergoes a quasi-static process, which is depicted by a straight line joining points \(\left(\mathrm{V}_{0}, \mathrm{~T}_{0}\right)\) and \(\left(2 \mathrm{~V}_{0}, 3 \mathrm{~T}_{0}\right)\) in a V-T diagram. What is the value of the heat capacity of the gas at the point \(\left(\mathrm{V}_{0}, \mathrm{~T}_{0}\right) ?\)
