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

Which of these statements is not true air has mass air exerts pressure air composes matter air contains mold?
air is composed OF matter
What is the relationship between air pressure and flight?
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.
Which are examples of simple measurements used for a basic weather forecast?
B. Temperature C. Air pressure D. Relative humidity
What is a glide give 2 examples?
The doors glide effortlessly on the tracks. The birds glide on the high air currents.
How will you show that air has maximum compressibility?
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?
-- Pressure -- Wind
Air exerts pressure because it has?
weight
How do you know that air exerts pressure?
Because the pressure can be measured with a barometer.
Dry air exerts less pressure than air that has What?
devin in it
What is exerting pressure?
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.
Can you give me some examples of air pressure?
A straw. If u suck the air pressure decerases and the liquid rushes in.
How much air pressure exerts in your body?
1 atm
What pressure does cold air exert?
Cold air exerts a low pressure. That is why cold air falls and hotter air rises above it.
Dry air exerts less pressure than air that has?
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.
Cold air exerts more blank than warm air?
air molecules in cold air exert more pressure because they are closer together and collide more often
Dose air in the atmosphere exert pressure on earths surface?
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.
What experiment proves that air exerts pressure?
Blowing up a balloon.
