Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C (68 °F), a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space. In an incident on January 12, 2006 at Texas A&M University , the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed.
At first, liquid air, self-enriched by standing (nitrogen has a lower boiling point and evaporates preferentially) was used, but pure liquid oxygen gives better results. A mixture of lampblack and liquid oxygen was measured to have a detonation velocity of 3,000 m/s, and 4 to 12% more explosive power than dynamite. The long duration of the ...

Nitro compounds are explosive because although the diatomic form of nitrogen is very stable—that is, the triple bond that holds N 2 together is very strong, and therefore has a great deal of bond energy—the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and other atoms in nitro compounds are weak by comparison.
