A rigid vessel(x) of volume $0.50{\mathrm{m}}^3$ containing ${\mathrm{H}}_2$ at $27^{\circ }\mathrm{C}$ and a pressure of $611\times 10^3$ Pa is connected to a second rigid vessel (y) of volume $0.75{\mathrm{m}}^3$ containing Ar at $37^{\circ }\mathrm{C}$ at a pressure of $1222\times 10^3\mathrm{Pa}$. A valve separating the two vessels is opened and both are cooled to a temperature of $127^{\circ }\mathrm{C}$. What is the ratio of average momentum along X -direction per molecule in the vessel ' Y ' at $27^{\circ }\mathrm{C}$ to $127^{\circ }\mathrm{C}$ ? $\mathrm{R}=1/12\mathrm{L}\mathrm{atm}/\mathrm{K}$ mole. $101.3\times 10^3\mathrm{Pa}=1\mathrm{atm}$.
