Code Number: 4C40.10

Demo Title: Sublimation of Dry Ice

Condition: Good

Principle: Change of State, Phase Changes

Area of Study: Thermodynamics

Equipment:

Dry Ice, plastic beaker.

Procedure:

Make some dry ice and place it into a plastic beaker. When you are ready just dump the dry ice directly onto the lecture bench and observe that there is no liquid accumulation during the sublimation process except for some small amount of water that condenses because of the temperature of the bench.
