Which amongst the following options is correct graphical representation of Boyle's Law?
$P=nRT\cdot\frac{1}{V}$ gives a straight line through the origin on a P vs $\frac{1}{V}$ plot.
$PV=nRT$ $P=nRT\cdot(1/V)$ Plot of $P$ vs $(1/V)$ would be a straight line passing through origin having slope $=nRT$. At high temperatures, $P$ vs $(1/V)$ would have greater slope.

A vessel contains 3.2 g of dioxygen gas at STP (273.15 K and 1 atm pressure). The gas is now transferred to another vessel at constant temperature, where pressure becomes one third of the original pressure. The volume of new vessel in L is: (Given - molar volume at STP is 22.4 L)Moles of $O_2=\frac{3.2}{32}=0.1$ mol. Volume at STP $=0.1\times22.4=2.24$ L. By Boyle's law, $P_1V_1=P_2V_2 \Rightarrow 1\times2.24=\frac{1}{3}V_2 \Rightarrow V_2=6.72$ L.

Choose the correct option for graphical representation of Boyle's law, which shows a graph of pressure vs. volume of a gas at different temperatures.According to Boyle's law, $P \propto \frac{1}{V}$ at constant temperature, so each isotherm is a rectangular hyperbola.
At a given pressure, $V \propto T$, so the isotherm for the higher temperature lies farther from the axes: 600 K above 400 K above 200 K.
