State a hypothesis based on the following questions: can air pressure be strong enough to crush an aluminum can? as an aluminum can is heated with water, what will happen to it when it is suddenly immersed in a bath of cold water?

Please see below.

Explanation:

Yes, although normal air pressure does not commonly crush an aluminum can, if it is allowed to increase its pressure it will crush the can, because air is a fluid, a mix of gases and they have a mass that can be applied to the can if gravity is artificially increased.

When an aluminum can is heated it will expand because metals expand with heat. When it is suddendly immersed in cold water the aluminum will again shrink because metals contract when cold is applied.
