• # question_answer 46) 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 YB)  half of that in YC)  twice of that in YD)  Eight times of that in Y

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