UH.I dont know u tell me hahahahahah!!
air molecules in cold air exert more pressure because they are closer together and collide more often
Water is more dense than air is.
Fluids have a higher density than air and therefore exert more pressure than air.
air pressure
yes
Yes. (see - barometer)
nimple
Yes, high pressure systems are associated with warmer air.
Cold air has more molecules occupying space than warm air, therefore it has high pressure.
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.
Cool air has more pressure because it's particles are condenced and warm air has less air pressure because the particles in it are more spread out.
