# A gas will approach ideal behaviour at :

$\begin{array}{1,1}(a)\;Low\;temperature\;and\;low\;pressure\\(b)\;Low\;temperature\;and\;high\;pressure\\(c)\;High\;temperature\;and\;low\;pressure\\(d)\;High\;temperature\;and\;high\;pressure \end{array}$

Real gases approach ideal gas behaviour at high temperature and low pressure
