What caused the can to crush?

What caused the can to crush?

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.

Why did the can crush in the experiment?

What caused the can to collapse? When you heated the can you caused the water in it to boil. Cooling the can caused the water vapor in the can to condense, creating a partial vacuum. The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it.

How can air pressure crush a soda can?

Lowering the pressure inside a pop can by heating it up creates a situation in which the pressure of the atmosphere can crush the pop can. This happens because the small amount of water that is placed inside the pop can becomes water vapour when it is heated up and displaces the air inside the can.

Why does can crush in cold water?

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. Since the air pressure outside the can is stronger than that inside the can, it causes the can to collapse.

How much force does it take to crush a can?

An actual testing of the beverage can crusher of the present invention, 50 pounds was the maximum force input required to fully crush a seamed steel beverage can whereas the force required to crush all aluminum beverage cans ranged from 5 pounds to 20 pounds.

Can Crush in cold water?

Why do cans crush in cold water?

Why can you crush a can with your hand?

The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it. A can is crushed when the pressure outside is greater than the pressure inside, and the pressure difference is greater than the can is able to withstand. You can crush an open aluminum can with your hand.

What happened when the air inside the can was crushed?

However, in this experiment, the air was driven out of the can and replaced by water vapor. When the water vapor condensed, the pressure inside the can became much less than the air pressure outside. Then the air outside crushed the can. When the water vapor inside the can condensed, the can was empty.

Why did the can crush when coolcooled?

Cooling the can caused the water vapor in the can to condense, creating a partial vacuum. The extremely low pressure of the partial vacuum inside the can made it possible for the pressure of the air outside the can to crush it.

What happens when you crush a can of water?

The can will loudly implode. If one is available, use a can that has already has the word “Crush” on it. This demonstrates phase change and the effect of unbalanced pressure. When the water in the can is heated, it changes to steam.
