Consider the following properties :
$\begin{array}{cc}\
&\text{P. temperature} & \text{Q. specific gravity} \\
&\text{R. chemical potential} & \text{ S. volume} \\
\\ \end{array}$
The option which lists $ALL$ the intensive properties is
- $P$
- $P$ and $Q$
- $P$, $Q$ and $R$
- $P$, $Q$, $R$ and $S$
