Answer 1

Answer:

The hot gas molecules are the same pressure as the air outside the can. When the can is placed in cold water upside down, the hot gas water molecules are cooled very rapidly. Some of the gas molecules are condensed back into liquid water so there are less molecules of water in the gas phase inside the can.

Answer 2

Answer:

The pressure made by the air around us is known as is known as atmospheric pressure. When the inverted can is placed in cold water, the steam condenses, leaving the can mostly empty, and thus with a very low pressure inside of it. The difference between the low pressure inside and the atmospheric pressure outside exerts an inward force on the walls of the can, causing it to implode.
