Q. The liquefaction behaviour of temporary gases like $CO_{2}$ approaches that of permanent gases like $N_{2},\ O_{2}$ etc, as we go to
A) Below critical temperature
B) Above critical temperature
C) Above absolute zero
D) Below absolute zero
Explanation
(b)
Gases for which intermolecular forces of attraction are small such as $N_{2},\ O_{2}$ etc have low value of $T_{c}$, thus liquefied above critical temperature
