Helium is suitable for gas thermometry at low temperatures because of its ...

Arrange the following gases in increasing order of van der Waals constant '$a$':
$A$. $Ar$; $B$. $CH_4$; $C$. $H_2O$; $D$. $C_6H_6$
Choose the correct option from the following:

Van der Waals's equation of state is obeyed by real gases. For $n$ moles of a real gas,the expression will be :-

The van der Waals constants for $HCl$ gas are $a = 3.6 \ atm \ L^2 \ mol^{-2}$ and $b = 40 \ mL \ mol^{-1}$. The critical temperature of the gas is : ............. $K$ [ $R = 0.08 \ atm \ L \ K^{-1} \ mol^{-1}$ ]

Under which of the following conditions does a real gas behave most like an ideal gas?

Real gases show deviation from ideal behavior. Explain with examples.
