One mole of an ideal gas is initially at \(300\ \text{K}\) and \(1.0\ \text{atm}\). The gas is heated at constant pressure while doing work on a piston. During the heating the gas does \(250\ \text{J}\) of work on the surroundings. The molar heat capacity at constant pressure is \(C_{p}=29.1\ \text{J mol}^{-1}\text{K}^{-1}\). Assuming the process is quasistatic, find the final temperature of the gas (in kelvin).
