Critical temperature of $CO_2$ is $27.5^{\circ} C$.

Vedclass · Answer

(B) The critical temperature of $CO_2$ is $31.1^{\circ} C$ $(304.1 \ K)$,not $27.5^{\circ} C$. Therefore,statement $B$ is incorrect.At Boyle temperature,the effects of attractive and repulsive forces balance out,making the gas behave ideally over a range of pressure.Above the critical temperature,gases cannot be liquefied by pressure alone,and they exhibit behavior closer to ideal gases as temperature increases.For $H_2$ and $He$,the compressibility factor $Z$ is always greater than $1$ at room temperature because the repulsive forces dominate due to their small molecular size.
