Question

A vessel contains 1 mole of O2 gas (molar mass 32 ) at a temperature T . The pressure of the gas is p . An identical vessel containing one mole of the gas (molar mass 4 ) at a temperature 2T has a pressure of (A) (p/8) (B) p (C) 2p (D) 8p

pV=nRT or p=(nRT/V) or p propto T V and n are same for both gases. Therefore, if T is doubled, pressure also becomes two times i.e. 2p

Q. A vessel contains $1 m o l e$ of $O_{2}$ gas (molar mass $32$ ) at a temperature $T$ . The pressure of the gas is $p$ . An identical vessel containing one mole of the gas (molar mass $4$ ) at a temperature $2 T$ has a pressure of

$\frac{p}{8}$

$p$

$2 p$

$8 p$

$p V = n RT$
or $p = \frac{n RT}{V}$
or $p \propto T$
$V$ and $n$ are same for both gases. Therefore, if $T$ is doubled, pressure also becomes two times i.e. $2 p$

Q. A vessel contains 1mole of O2​ gas (molar mass 32 ) at a temperature T . The pressure of the gas is p . An identical vessel containing one mole of the gas (molar mass 4 ) at a temperature 2T has a pressure of

pV=nRT or p=VnRT​ or p∝T V and n are same for both gases. Therefore, if T is doubled, pressure also becomes two times i.e. 2p
