When liquid nitrogen is placed in a sealed container, the pressure of the container increases until the container explodes. The energy released in the explosion can be used to launch a bucket high into the air. Analyzing the experiment using the ideal gas law gives results that are inconsistent with observations. Use of the van der Waals equation yields reasonable results.
