Dry Ice - Sublimation

mediumblue

Summary

Professor Hal Sosabowski demonstrates a simple yet effective experiment which reveals several properties of solid carbon dioxide, which teachers can use in Key Stage 3/4 science lessons.

Hal shows how clouds of water vapour can be formed, how carbon dioxide is denser than air, how a gas occupies much more volume than a solid, and how dry ice sublimes - turning directly from a solid to a gas without becoming a liquid.

Professor Hal Sosabowski is a committed chemistry educator who shows how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
