Pressure.

Explanation:

The #ul"cold"# water outside the can has #ul"higher"# pressure than the #ul"less"# air inside the can because the #ul"molecules"# of cold water are #ul"closer"# together and press #ul"more"# on the #ul"sides"# of the can. The #ul"hot"# #ul"air"# molecules are spread #ul"far"# apart and do not press on the #ul"sides"# of the can with as much #ul"force"#. The #ul"closer"# water molecules crush the can.
