As a characteristic property of gases, air compresses more easily as compared to liquids like water. This is because the intermolecular force of attraction among the gas particles is lesser than liquid particles. Hence they tend to have more space and can be compressed more easily.
Water is more dense and it's particles are more massive/heavier;
water
By definition liquids are incompressible. Water in its liquid state is therefore incompressible.
I say cold air because the cold air unlike hot air comes together and sinks while hot air spreads out and rises making cold air create more pressure
Yes. Actually water is a fairly unique substance as it does not compress at all, and expands when it turns to a solid while all other substances known to man compress when turned to a solid.
air is composed OF matter
imagine that all the air around you is puting pressure on you. Then, when you go into a fluid, you can feel the pressure of the air and the water. The deeper you go, the more pressure is on top of you and eventually, you will get crushed.
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.
Atmospheric pressure is reduced with increasing water vapor because the water has a lower molecular weight than dry air. The same number of molecules occupy a given volume at a given pressure, so the total mass of water vapor laden air is lower than dry air. If you add up the weight of a column of the wet air it will weigh less than the same column filled with dry air, hence, wet air has a lower air pressure.
Pressure doesn't change when you change substance, 120 PSI in water equals 120 PSI in air.
DENSER MORE PRESSURE PRESSURE PRESSURE LOOK AT SCIENCE TEXT BOOK DONT CHEAT ON WIKI Water has more density than air.
air molecules in cold air exert more pressure because they are closer together and collide more often

Because your hand replaces the column of air which was 'pressing' on the content of the bottle. Your hand exerts more pressure than the air.(: :) :p P:
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.
Because the air molecules are packed closer together in cold air.
-- Pressure -- Wind
weight
They shake because, the water exerts pressure when running in the pipes
Because the pressure can be measured with a barometer.
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.
