1. Filling a test tube with water and putting a piece of plastic on it and turning it upside down.(the water does not come out).
1.means that there is a pressure holding the water in the tube so two proves.
2. Putting in air in a syringe and putting a cap on the end, later holding the cap in placegently pushing the plunger down with your thumb and releasing the plunger.
2. proves it air pus the cap out so it means it exerted a pressure.
3. Putting an unused balloon inside a bottle and then trying to blow it up while the balloon is in the bottle.
3. if u exert enough pressure it will break the bottle so 3 is also checked
this is Radhika hope u lik it :D
you put a cap loosely on a soda bottle.
then you stomp on it :o
when we blow a balloon and leave it
air is composed OF matter
Air exerts pressure in the same way that water exerts pressure on a diver. Air has weight, and because we are at the bottom of a blanket of air that surrounds the earth, the weight of that air is pressing down on us (creating pressure). If you go under water, you'll feel the additional pressure created by the weight of the water above you.
B. Temperature C. Air pressure D. Relative humidity
The doors glide effortlessly on the tracks. The birds glide on the high air currents.
by showing at what point it stops behaving like air (the pressure at which it condenses to a liquid).You can show that air has maximum compressibility using 3 syringes with one sealed with water, the other with air, and the other with chalk whereby the one with air will allow compression to the highest degree compared to the rest.
When air exerts a force, it is called air pressure. Air pressure is the force exerted by the weight of air above a given point.
weight
Air exerts pressure because it contains molecules that are constantly in motion and colliding with surfaces around them. These collisions create a force per unit area, which results in pressure being exerted by the air. This pressure can be measured using devices like barometers or manometers.
devin in it
Force exerts pressure. For example: At the surface of the Earth the column of air in the atmosphere above an area has a mass that exerts a force (due to gravity) on that surface area.
Examples of air pressure include the pressure exerted by the atmosphere on the Earth's surface, the pressure inside a sealed container like a balloon or a tire, and the pressure of the air in your lungs when you breathe in and out.
1 atm
Cold air exerts a lower pressure compared to warm air because the molecules in cold air are moving more slowly and are closer together. This results in a decrease in the air pressure.
Dry air exerts less pressure than air that has a higher humidity. In general, air pressure is the sum of the individual pressures of gases present in the air. Dry air lacks any water vapor pressure in the air. Therefore, any air with a humidity above 0% has a higher pressure than dry air.
air molecules in cold air exert more pressure because they are closer together and collide more often
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
One experiment that proves that air exerts pressure is the collapsing can experiment. In this experiment, a small amount of water is boiled in a can, and the can is then sealed. As the steam cools and condenses, it creates a vacuum inside the can, causing the outside air pressure to crush the can. This demonstration shows that air exerts pressure.
