On Friday Brian Smith '07 joined our Upper School chemistry classes for hands on experiments in the science lab.
Students were posed questions such as: What is air? What are the properties of liquid nitrogen? The groups discussed Le Châtelier's Principle and the Haber Process. Other topics included atmospheric composition (O2, N2, Ar), uses of the gases, liquid nitrogen temperature, hazards and safety concerns around gases (N2, O2), effects of cryogenic temperatures on different materials, thermal expansion and contraction, changes of state - physical change, and cryogenic distillation.
