Presentation transcript:

Carbon dioxide Dry ice experiments

.04% of our atmosphere One pound of solid Dry Ice = 8.3 cubic feet of carbon dioxide gas!

Phase Change

Sublimation Water Gas boils at 100° C Liquid at room temperature Solid freezes 0° C Carbon Dioxide Gas at room temperature Liquid jumps from solid to gas! Solid freezes at ° C

Sublimation  Sublimation is the changing of a solid directly to vapor without first melting.
