Choose the correct option for graphical representation of Boyle's law, which shows a graph of pressure vs. Volume of a gas at different temperature.

Boyle's Law states $P\propto 1/V$ at constant $T$. The graph of $P$ vs $V$ is a rectangular hyperbola. Since $PV=nRT$, at a constant volume, as temperature increases, pressure increases. Therefore, the curve for a higher temperature ($T_3$) will be above the curve for a lower temperature ($T_2$).Correct graph: Option B.
