Noble gases have very low boiling points. Why?

Solution
noble gas have configuration 1s2 2s2 3p6 thus it have complete shell configuration hence can exist in monoatomic form. Noble gases being monoatomic have no interatomic forces except weak dispersion forces and therfore, it is difficult to liquify them. As a consequence, they have low boiling points.
