Question
Shows plot of $\frac{P V}{T}$ versus $P$ for $1.00 \times 10^{-3} \mathrm{~kg}$ of oxygen gas at two different temperatures: Which is true, $T_1>T_2$ or $T_1<T_2$ ?
✓
Answer
The dotted plot in the given graph represents an ideal gas. The curve of the gas at temperature $T_1$ is closer to the dotted plot than the curve of the gas at temperature $T_2$. A real gas approaches the behaviour of an ideal gas when its temperature increases. Therefore, $\mathrm{T}_1>\mathrm{T}_2$ is true for the given plot.
