In a Jolly's differential calorimeter one of the spheres of volume 1 litre was filled with experiemental gas at 10 atmospheric pressure. When steady state was attained, the excess of steam that condensed on this sphere was `0.378g`. Calculate the specific heat capacity of the gas at constant volume. (Initial temperature of gas `=15^(@)C, L` of steam of `100^(@)C=540xx10^(3)cal kg^(-1), J=4.2 J cal^(-1)` and density of gas at 1 atmospheric pressure `=0.8kgm^(-3)`)
