When 16.0 J was added as heat to a particular ideal gas, the volume of the gas changed from 57.5 cm³ to 121 cm³ while the pressure remained constant at 1.15 atm. (a) By how much did the internal energy of the gas change? If the quantity of gas present is 1.65 x 103 mol, find the molar specific heat of the gas at (b) constant pressure and (c) constant volume.
