Question

The figure shows plot of $\frac{P V}{T}$ versus $P$ for a given mass of gas at two different temperatures $T_1$ and $T_2$. Identify the incorrect statement.

Professor PC Thomas Classes · Answer

The intercept on the $y$-axis is given by
$
\frac{P V}{T}=n R=\left(\frac{m}{M}\right) R
$
It depends on the molar mass $M$ of the gas.
