how can the empty soda can just go from a non freezing to a freezing and just crush?

Question

you have an empty can you let it boil put it in cold water up side down and it crushes why please use volume air pressure gas and the charles law oh evaporation and partictmovemont

Answer 1

You don't have enough information in your question. If you boil water in a can, that implies that there is hole in it. If you assume that the hole is in the top and you boil the water and eliminate most of the air in the can, then the can is filled with steam. Putting the can in cold water will condense the steam and lower the pressure in the can. If the hole in the can is under water, then water would enter the can to equalize the pressure. If the hole is not under water, air will enter the can to equilize pressure. The can would only collapse if the hole were small so that water or air entering the can could not equalize the pressure fast enough. That means that you had to be careful boiling the water or the can would have exploded then.

Answer 2

Basically, when the air inside the can cools, the pressure drops because the volume decreases (and no more air can get in). That is Boyle's Law ( the volume of a gas is inversely proportional to the pressure). This means the pressure inside the can is now less than the atmospheric pressure outside, causing the can to collapse.
