Identifier: T: H - 025

Styrofoam Cooler, Dry Ice, Tongs

Concept Overview:

  1. Visualization of the P vs. T graph for Carbon Dioxide
  2. Sublimation

Lecturer Procedure

Step(s) to Follow

  1. Set a few pieces of dry ice on the desk.
  2. Use the P vs. T diagram to explain what is happening at room temperature and standard pressure

Expected Result

The dry ice will not melt - it will change directly from a solid to a gas (sublimination)
