Today we looked at phase changes and states of matter. We reviewed condensation, evaporation, sublimation, freezing and melting. We did a demonstration with a soda can, water, and a hot plate. As the water vapor condensed in the can it created a lower pressure inside the can and the atmospheric pressure crushed the can. Here are links to two videos demonstrating the same process.
Can crush video and train car implosion video.
