Question

An ideal monatomic gas of n moles is taken through a cycle $W X Y Z W$ consisting of consecutive adiabatic and isobaric quasi-static processes, as shown in the schematic $V - T$ diagram. The volume of the gas at $W, X$ and $Y$ points are, $64 cm^{3}, 125 cm^{3}$ and $250 cm^{3}$ , respectively. If the absolute temperature of the gas $T_{W}$ at the point $W$ is such that $n R T_{W} = 1 J$ (R is the universal gas constant), then the amount of heat absorbed (in J) by the gas along the path $X Y$ is $____$
