Q.
$V\ versus\ T$ curves at constant pressure $p_{1}$ and $p_{2}$ for an ideal gas are shown in figure. Which is correct?
A) $p_{1} > p_{2}$
B) $p_{1} < p_{2}$
C) $p_{1} = p_{2}$
D) All of these
Explanation
(b)
At constant pressure $V \propto T$, but according to Gay Lussac’s law the pressure of a given mass of a gas is directly proportional to the absolute temperature. Thus,
$p_{1} < p_{2}$
