In the V-T graph shown in figure:
Column-I Column-II
i. Gas A is … and gas B is … p. monoatomic, diatomic
ii. $\frac{P_{A}}{P_{B}}$ is q. diatomic, monoatomic
iii.. $\frac{n_{A}}{n_{B}} is$ r.
> 1
s. < 1
t. cannot say any thing
Now, match the given columns and select the correct option from the codes given below.
Codes

Moderate

Solution

From given V-T graph we cannot tell the nature of gas. Slope of V-T graph = $\frac{nR}{P}$
From graph ${(\frac{nR}{P})}_{A} > {(\frac{nR}{P})}_{B} \Rightarrow {(\frac{n}{P})}_{A} > {(\frac{n}{P})}_{B}$
$\Rightarrow$ Cannot say anything about $\frac{n_{A}}{n_{B}} and \frac{P_{A}}{P_{B}}$
