Question

difference between air pressure and liquid pressure in 2 points

Answer 1

The difference is that water is an incompressible fluid — its density is almost constant as the pressure changes — while air is a compressible fluid — its density changes with pressure. ... Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid)

Answer 2

➣ AnSwer :-

⟶ Air Pressure :-

• Air pressure is caused by the weight of the air molecules above.
• Even tiny air molecules have some weight, and the huge numbers of air molecules that make up the layers of our atmosphere collectively have a great deal of weight, which presses down on whatever is below.

⟶ Liquid Pressure :-

• Liquid pressure is the increase in pressure at increasing depths in a liquid.
• This pressure increases because the liquid at lower depths has to support all of the water above it.
