Solution

The correct option is A $P_{1} > P_{2}$
According to Charle's law
$V \propto T$ or $\frac{V}{T} =$ constant $= \frac{1}{P}$
As in graph, slope at $P_{2}$ is more than slope at $P_{1}$ ,
$∴$ $P_{1}$ > $P_{2}$

The correct option is A P1>P2According to Charle's lawV∝T or VT= constant =1PAs in graph, slope at P2 is more than slope at P1,∴ P1>P2
