Predict which would have a higher boiling point, NH3 or PH3, and explain.
Discuss the forces involved.
and
How do the forces relate to boiling point?

You need to draw out the lewis structures of each molecule and observe what kind of intermolecular forces each one has. After telling which one each one was you need to recall that some intermolecular forces are stronger than others. the strongest intermolecular force is hydrogen bonds while the weakest are london dispersion forces. Whichever one has the stronger forces will have a higher boiling point since it will take more energy to break those bonds and boil it.
