Molar\ Heat\ Capacity\ at\ constant\ Volume\ = \\ \ \ C_v of methane (CH_4) = 27.1 J K^{-1} mol^{-1}, \ \ \ \ \gamma = 4/3 \\ \\ Energy = n C_v \Delta\ T =\ 2\ moles\ *\ 27.1 J\ K^{-1}\ mol^{-1}\ *\ 1 degK \\ \\ \ \ =\ 54.2 J \\

The work done is zero by the pressure as the volume is kept constant. The energy goes goes into heating the gas and that goes as the Internal energy in the gas.
