What happens if nearly saturated air experiences a quick,significant temperature drop?

As cumulus clouds grow they shade the ground from the Sun.This acts to

Why is it usually necessary for an air mass to rise if it is to produce precipitation?

At the same level and temperature in the atmosphere,is moist air lighter or heavier than dry air?
