Vedclass · Answer

(D) The boiling point of noble gases depends on the magnitude of interatomic forces of attraction. $He$ has the smallest atomic size and the lowest polarizability among all noble gases. Consequently,the van der Waals forces of attraction between $He$ atoms are extremely weak,resulting in the lowest boiling point of $4.2 \ K$.

The reason for the lowest boiling point of $He$ is...
