\(7 \mathrm{~mol}\) of an ideal gas \(\left(C_{V}=5 \mathrm{cal}\right)\) was initially at \(30^{\circ} \mathrm{C}\) and \(2 \mathrm{~atm}\). The gas was transferred to the state when the temperature is \(110^{\circ} \mathrm{C}\) and pressure \(12 \mathrm{~atm}\). Determine the change in entropy of the process.
