To prepare liquid nitrogen through the process of liquidation, molecular energy from Nitrogen is removed. So the liquid has little to no energy and is also a freezing temperature. When the liquid is exposed to regular conditions, the molecules inside the liquid start absorbing the heat energy from its surroundings causing it to boil. Liquid nitrogen even boils at temperatures below zero!!
For more interesting facts and experiments with liquid nitrogen, come and check out Sub-Zero beginning July 3rd and only offered on Saturdays throughout the summer!!
