Asealed tank contains 29 moles of an ideal gas at an initial temperature of the pressure of the gas is increased until the final pressure equals 1.9 times the initial pressure. the heat capacity at constant pressure of the gas is what is the heat absorbed by the gas? let the ideal-gas constant r = 8.314 j/(mol • k).
