• The specific heat of hydrogen gas at constant pressure is ${{C}_{P}}=3.4\times {{10}^{3}}cal/kg{{\,}^{o}}C$ and at constant volume is ${{C}_{V}}=2.4\times {{10}^{3}}cal/kg{{\,}^{o}}C.$. If one kilogram hydrogen gas is heated from ${{10}^{o}}C$ to ${{20}^{o}}C$ at constant pressure, the external work done on the gas to maintain it at constant pressure is
