Crushing the Can

Crushing the Can

Science Background:

·         Inside the can at room temperature (with the water inside) is at the same air pressure as the air outside the can

·         Water expands to about 600 times its liquid volume when heated above its boiling point (100 degrees)

·         Water expands and pushes almost all of the air outside of the can. The water vapor inside the can has the same pressure as the air outside the can

·         Hot water vapor condenses into liquid water when cooled

·         The volume of the condensed water is approximately 600 times less than the previous hot water vapor volume
