Help with chemistry please? 10 pts?

The can gets all squished. This is because, when you heat up the can, the water in there boils, causing some of the air in the can to be replaced with water vapor. When you invert the can quickly into the ice bath, the ice cools the can and the environment inside the can. When the water vapor in the can cools, it returns to liquid state, and so the volume of the can decreases (the can squishes) because there is less gas in the can (the water vapor gas became liquid and joined the liquid in the ice bath). The can becomes almost a vacuum, and it sucks itself inward (it can't get any more air because its only opening is below the water level of the ice bath). I hope this helps!
