Where the Ideal Gas Law Breaks

You'll learnwhy real gases stray from PV = nRT, and why they stray worst when they are crowded and cold.

Squeeze one mole of nitrogen to 600 atmospheres and the volume you measure is about sixty percent bigger than the gas law predicts. The gas is behaving normally; the law made two assumptions about the particles, and both have just stopped being true. Twelve short steps; press Next for each one.

ONE NITROGEN CURVE · HOW FAR IT STRAYS FROM PV = nRT
Before you start
What you're looking at
One mole of nitrogen being squeezed, and a chart of how far it strays from the gas law.
The question
Why does the measured volume come out bigger than PV = nRT predicts?
