Can Crusher

The video explains atmospheric pressure and demonstrates its strength through an experiment. A sealable can is heated with water to create water vapor, which forces out air. Once sealed and cooled, the vapor condenses, creating a vacuum that allows atmospheric pressure to crush the can. This illustrates the significant force of atmospheric pressure.

Why is it important to use protective gloves during the experiment?

How does the pressure inside the can change after sealing it?

What is the final observation made about atmospheric pressure in the experiment?
