    Two flasks X and Y have capacity 1L and 2L respectively and each of them contains 1 mole of a gas. The temperatures of the flasks are so adjusted that average speed of molecules in X is twice as those in Y. The pressure in flasks X would be

    A)  same as that in Y

    B)  half of that in Y

    C)  twice of that in Y

    D)  Eight times of that in Y

    Correct Answer: D

    Solution :

    \[P=\frac{1}{3}\,\frac{mn{{u}^{2}}}{\upsilon }\] \[\frac{{{P}_{s}}}{{{P}_{y}}}=\frac{{{n}_{s}}{{u}_{x}}{{u}_{y}}}{{{n}_{y}}{{u}_{u}}{{\upsilon }_{x}}}=\frac{\left( {}^{{{N}_{0}}}/{}_{1000} \right)}{\left( {}^{{{N}_{0}}}/{}_{2000} \right)}\times 2\times \frac{2}{1}=8\]
