What was happening to the can and the particples inside the can? (step by step in the vid attatched)

Experiment: Air Pressure Can Crush

Explanation:

The picture shows a crushed can inside a bowl with iced water.

This experiment consists on pouring a small amount of water inside a can, heating the can directly on a kitchen burner, using a heat insulating clamp, and placing the can with the open end face down in a bowl with iced water.

The particles inside the can, when heated on the kitchen burner will expand, since the heat supplied increases the kinetic energy of the particles vigorously. Since the can is open, the pressure inside the can equals the pressure outside the can (the atmospheric pressure).

When the can is put face down in contact with the iced water, the air inside the can will cool down rapidly, causing the pressure (according to Boyle's law) to decrease quickly.

Now, there will be a huge difference between the atmospheric pressure and the pressure inside the can, which will generate a net force pointing radially toward the can strong enogh to crush the can.

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
