    Six moles of oxygen gas is heated from 20∘20^\circC to 35∘35^\circC at constant volume. If specific heat capacity at constant pressure is 8 cal mol−1 k−18\ \mathrm{cal\,mol^{-1}\,k^{-1}} and gas constant is 2 cal mol−1 k−12\ \mathrm{cal\,mol^{-1}\,k^{-1}}. The change in internal energy of the gas is
