Make Liquid Oxygen in Your Class
French, M. M. J.; Hibbert, Michael
Physics Education, v45 n3 p221-222 May 2010
Oxygen is one of the component gases of air at room temperature, making up around 20% of the atmosphere. But can oxygen be liquified? This article details a method for making small amounts of liquid oxygen in the classroom if there is no access to a cylinder of compressed oxygen gas, and two methods for identifying the fact that it is liquid oxygen as opposed to liquid nitrogen. (Contains 3 figures.)
