I4-13. Change Of State Of Ln - Popping Can Lid
To show the increase in volume which accompanies the transition from liquid to gaseous nitrogen.
Liquid nitrogen, can with plastic lid.
Pour some liquid nitrogen into a can and install the plastic lid. The liquid nitrogen heats up, changes to a gas, and blows the lid. Repeat for students who blinked.
