We know, PV =( m / M ) RT Given the flasks have same volume, and mass m =1 gm for all the gases, the temperature attained is also same. Hence the equation can be reduced to, PM=Constant, where M is the molecular weight. since M 1< M 2< M 3 ∴ P 1> P 2> P 3

Q. Three flasks of identical volume are filled separately by (a) 1 gram of $H_{2}$ (b) 1 gram of $O_{2}$ (c) 1 gram of $C O_{2}$ . They are immersed in a tank of water so that all of them attain same temperature. The pressures $P_{1}, P_{2}$ and $P_{3}$ have the o

$P_{1} > P_{2} > P_{3}$

$P_{1} = P_{2} = P_{3}$

$P_{1} < P_{2} < P_{3}$

$P_{3} > P_{1} > P_{2}$

We know, PV $= \frac{m}{M} RT$
Given the flasks have same volume, and mass $m = 1 g m$ for all the gases, the temperature attained is also same.
Hence the equation can be reduced to, PM=Constant, where $M$ is the molecular weight.
since $M_{1} < M_{2} < M_{3}$
$∴ P_{1} > P_{2} > P_{3}$
