Answer
Bond polarity explains why ammonia condenses at a higher temperature than nitrogen at standard pressure. In its gaseous form, nitrogen is non-polar. On the other hand, ammonia is. This causes attractions between the polar sections of the ammonia atoms, causing them to get closer together, and thus, to condense at a higher temperature.
