When the air is pumped out of the can, the pressure inside the can becomes significantly lower than the external atmospheric pressure. The higher external pressure then causes the can to collapse. This is due to the unequal forces acting on the can from the outside and inside, leading to the can's deformation.

Why does a sealed empty tin can collapse when the air inside the can is pumped out?
When the air inside the can is pumped out, there is a decrease in pressure inside the can. The outside air pressure then pushes on the sides of the can, causing it to collapse. This happens because the higher pressure outside the can is not balanced by the lower pressure inside the can.
What is the explanation behind the can crusher experiment?
The can crusher experiment demonstrates the principle of air pressure. When the can is heated and then quickly cooled, the air inside the can condenses, creating a vacuum. The external air pressure then crushes the can.
Why does a pumped ball bounce higher than a flat ball?
A pumped ball bounces higher than a flat ball because the air pressure inside the pumped ball creates more rebound force when the ball hits a surface. This increased pressure allows the ball to store and release more energy upon impact, resulting in a higher bounce.
How does a can crush when you heat up the air inside then let it cool?
When you heat up the air inside a can, the molecules gain kinetic energy and move faster, increasing the pressure inside the can. When you quickly cool the can by submerging it in cold water, the air molecules lose energy and slow down, causing a decrease in pressure inside the can. The external atmospheric pressure then crushes the can as it is now greater than the pressure inside the can, resulting in the can collapsing.
What causes the air pressure inside an inflated balloon?
The elastic contraction of the rubber in the balloon's membrane causes the pressure in the air inside an inflated balloon. When you inflate a balloon, you have to expand the latex of the balloon, which stretches when filled with air from a pressure of 760 mm Hg to as high as 840 (about 10% higher than standard atmospheric pressure). If you inflate a non-elastic mylar balloon, it takes no effort: the air inside is at the same pressure as the air outside.
Why does a sealed empty tin can collapse when the air inside the can is pumped out?
When the air inside the can is pumped out, there is a decrease in pressure inside the can. The outside air pressure then pushes on the sides of the can, causing it to collapse. This happens because the higher pressure outside the can is not balanced by the lower pressure inside the can.
Does the air inside a fully pumped basketball have a lower or higher pressure than the outside?
The air inside a fully pumped basketball have a higher pressure than the air outside due to a greater number of gas particles per unit volume inside the ball than in the surrounding air.
How can air pressure be utilized to crush a can?
Air pressure can be used to crush a can by creating a difference in pressure inside and outside the can. When the can is heated and then quickly cooled, the air inside the can condenses, creating a lower pressure. The higher pressure outside the can then crushes it.
Why do tin cans get crushed if cooled after heated and closing is mouth?
Assuming the can can be sealed. When the can is heated the air inside it expands. If the can is then sealed and allowed to cool the air inside contracts which causes the pressure inside to drop. Because the outside air pressure is now greater it crushes the can.
When air is pumped into a tire?
When it is needed.The tire inflates when air is pumped in
What are Australian rules footballs made of?
The outside is leather with a rubber bladder on the inside which is pumped with air to inflate the ball.
Does the air inside a fully pumped basketball have a lower or higher pressure than the air outside?
the higher pressure is due to a greater number of gas particles per unit volume inside the ball then in the surrounding air.
What is the explanation behind the can crusher experiment?
The can crusher experiment demonstrates the principle of air pressure. When the can is heated and then quickly cooled, the air inside the can condenses, creating a vacuum. The external air pressure then crushes the can.
How can air pressure be used to crush a can?
Air pressure can be used to crush a can by heating the can and then quickly cooling it, causing the air inside to contract and create a lower pressure than the air outside. The higher outside air pressure then crushes the can.
Why do cans collapes if the air is removed from it?
Think of the air around us as a huge ocean of air that sits ontop of the land. Air has weight...incredible weight. If you take the air out of something, the there is a vacuum inside it and nothing to support it and the air pressure crushes it
What happens when all the air is pumped out of a sealed in can?
When all the air is pumped out of a sealed can, the can's internal pressure decreases significantly, causing it to collapse or implode due to the unequal pressure between the inside and outside of the can.
How can you crush a can using air pressure?
To crush a can using air pressure, you can heat the can with a heat source, then quickly submerge it in cold water. The rapid cooling causes the air inside the can to contract, creating a vacuum that crushes the can.
