Liquefaction of Gases

The critical temperatures of $C O_{2}$ and $C H_{4}$ gases are $31 . 1^{0} C$ and $- 81 . 9^{0} C$ . Which of the two has strong intermolecular forces and why?

The van dar Waal's parameters for gases W, X, Y and Z are:

Gas a(atm $l^{2} / m o l^{2}$ ) b(l/mol)
W $4.0$ $0.027$
X $8.0$ $0.030$
Y $6.0$ $0.032$
Z $12.0$ $0.027$

Which one of these gases has the highest critical temperature?

In an attempt to record critical temperature of some substances, the value of water has been missed out.

Will the value of $x$ be more or less than for $N H_{3}$ ? Reason out your answer.

The correct order of the values of critical temp, $T_{C}$ ; Boyle temp, $T_{B}$ and inversion temp, $T_{i}$ of a real gas is:

At a temperature less than Critical temperature, to liquefy a gas:

Which of the following statements on critical constants of gases are correct?
$I :$ Larger the $T_{c} / p_{c}$ value of a gas, larger would be the excluded volume.
$I I :$ Critical temperature $(T_{c})$ of a gas is greater than its Boyles's temperature $(T_{b})$ .
$I I I :$ At the critical point in the van der Waals' gas isotherm.
$(\frac{δ p}{δ V _{m}}) T_{c} = 0$
