Answerthe reason is that the molecules in air push in all directions down,up, and sideways. The air pushing down on top of your desk is balanced by the air pushing up on the bottom of your desk.

Why does in air pressure crush objects such as your desk?

Air pressure can crush objects like a desk because the weight of the air above the object creates a force pushing down on it. As the air pressure increases, this force becomes stronger, causing the object to collapse under the weight.


Why doesn and rsquot air pressure crush objects such as your desk?

Every day objects are surrounded by air, on all sides and inside, so all the force of the weight of the air acts equally in all directions.


Why doest air pressure crush objects such as a desk?

Because that air pressure is the same on all sides and inside objects. If you were to seal a container at the top of Mt. Everest, Then took it down to Sea Level, It might crush (depending on the strength of the container) because the air pressure inside would be much less (the same as at the Peak where you sealed it) then it is at sea level.


Can air crush?

Yes it can. Depending on the range of air pressure between earth and space


Why doesn't air pressure cursh objects?

Air pressure WILL crush objects. A standard experiment is to fill a 1 gallon can with water, and then closely fit a small diameter hose to the outlet. Invert the can, and if your hose was indeed sufficiently small, the water will drain out, and the can will collapse due to the air pressure from outside overcoming the strength of the can walls. Air pressure will not crush solid objects in general for they are already as dense as they can become.


Why doesnt air pressure crush objects?

There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.


How can a can crush science experiment be conducted to demonstrate the principles of air pressure and demonstrate the effects of atmospheric pressure on everyday objects?

To conduct a can crush science experiment demonstrating air pressure principles, follow these steps: Fill a can with a small amount of water and heat it on a stove until steam comes out of the opening. Quickly place the can upside down in a bowl of cold water. The sudden cooling of the steam inside the can creates a vacuum, causing the atmospheric pressure outside the can to crush it. This experiment shows how changes in air pressure can affect everyday objects like cans.


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.


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.


How does air pressure play a role in crushing a can?

When a can is crushed, the air pressure inside the can decreases, causing the higher air pressure outside the can to crush it.


Can air pressure crush cans?

a drinks can


How can the results of the can crushing experiment be used to demonstrate the effects of air pressure?

The results of the can crushing experiment can be used to show how changes in air pressure can cause the can to collapse. By heating the can and then quickly cooling it, the air inside the can condenses, creating a lower pressure compared to the outside air. This pressure difference causes the can to crush as the higher external pressure pushes in on it. This experiment illustrates how air pressure can have a significant impact on objects in our environment.
