Wet Dry Ice: Triple Point of CO2—ChemTopic™ Lab Activity


The solid form of carbon dioxide is called “dry ice” because it does not melt like ordinary ice, but rather sublimes directly from a solid to a gas. The liquid form of dry ice is not stable at “ordinary” pressures and temperatures (atmospheric conditions). With the Wet Dry Ice: Triple Point of CO2—ChemTopic™ Lab Activity, dry ice is allowed to sublime in a closed system, so the pressure will increase to a point where the liquid form of carbon dioxide can be seen. Available as part of the Solids and Liquids—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
