A sealed piston-cylinder contains \(0.05\,\text{mol}\) of an ideal gas at \(300\,\text{K}\) and a pressure of \(1.0\,\text{atm}\). The gas is heated at constant pressure \(1.0\,\text{atm}\) until a total of \(500\,\text{J}\) of heat has been supplied. The molar heat capacity at constant pressure is \(C_{p}=29\,\text{J\,mol}^{-1}\text{K}^{-1}\). (a) Find the final temperature of the gas. (b) Determine the final volume of the gas. (c) Calculate the work done by the gas during the heating process.
