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
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.
Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
weight
Exerting pressure is the act of applying force or weight on an object or surface. This pressure can cause a change in the state or shape of the object. Examples of exerting pressure include pushing, squeezing, or compressing an object.
devin in it
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.
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
The force that air exerts on a given area is called air pressure. Air pressure is the result of the weight of the air above the given area pressing down on it. This pressure can vary depending on altitude, weather conditions, and temperature.
air molecules in cold air exert more pressure because they are closer together and collide more often
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
Air pressure is generally lower in warm areas because warm air is less dense and therefore exerts less pressure on its surroundings. Cool air is denser and exerts more pressure, so areas with cooler temperatures typically have higher air pressure.
