So you have a sample of nitrogen that is a gas, right?  If you cool it, the first thing that is going to happen, once you cool it far enough, is that it will turn into a liquid.  This will have to be pretty cold, though.  The point at which gaseous nitrogen condenses and becomes a liquid is -196 Celsius!

This is the process of condensation -- just the same as if it were steam that cooled off and became water.  This is the process where the molecules lose too energy until they do not have enough left to overcome the intramolecular forces.  At this point, they can no longer be a gas.
