Why is the boiling point of helium lower than hydrogen? Helium has a lower boiling point because it is a single spherical atom. It has very little surface area, and is not very polarizable. Elemental hydrogen exists as a diatomic molecule (H2).
Why does helium have a low boiling point? This means that because a helium atom is smaller than a krypton atom, the IFA of helium must be weaker than the IFA of krypton. … If helium’s bonds are weaker, less heat/energy is required to break the bonds thus melting/boiling points are lower!

What boiling point of a liquid?
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).

Why does nh3 have a higher boiling point than ph3?
NH3 molecules makes strong intermolecular H bonding b/w themselves. But due to lesser electronegativity of larger PH3 molecules, they cannot form Hydrogen Bonding b/w themselves. In NH3, there is hydrogen bonding whereas in PH3 there is no hydrogen bonding. Therefore, the NH3 has higher boiling point than PH3.
