Crushing Pop Cans With Pressure

In the second part of the demonstration the Pepsi can was partially emptied and then heated. Unlike the first can, this can has a significant amount of vapors present due to the small amount of boiling Pepsi in the bottom of the can. As the second can is inverted in the cold water, the pressure inside the can drops even more dramatically than the first can, almost completely crushing the can. Temperature is still an important feature in
the second can; however, the presence of water vapor in the second means that condensation is also a factor. The condensation of water vapors reduces the number of gas molecules present, further reducing the pressure inside the can by decreasing the frequency of collisions. The difference in the degree to which the second can was crushed can be attributed to the contribution of condensation.
