Can Extreme Pressure Turn Gases into Liquids or Solids?

[toochaos]

im wondering in theory couldn't you put so much presure on a gas that the molocules couldn't move therefore creating a liquid or a solid ( i realize this would take a lot of pressure) but would it result in a liquid or no??

Of course, this happens all the time. Just look at a phase diagram for a substance, like water:

If you increase the pressure on water vapor while maintaining its temperature, it'll turn first into water, then into ice.

If I have liquid nitrogen contained in an extremely strong sealed container at room temperature, should I assume that the pressure is right at the boundary between liquid and solid nitrogen? If this is not the case, then how do I determine the pressure (quasi-theoretically)?

phase: liquid (i.e. density >> N₂ gas at rm. temp.)
temperature: 300 K
pressure: ?
