Liquid pressure = weight density x depth
When you swim under water, you can feel the water pressure acting against your eardrums. The deeper you swim, the greater the pressure. The cause of pressure is simply the weight of the water (and air) above pushing against you. If you swim twice as deep, there is twice the weight of water above, and twice the water pressure.
The pressure exerted by the liquid depends on density as well as depth. If you were submerged in a liquid more dense than water, the pressure would be proportionally greater.

When atmospheric pressure increases what happpens to the boiling temperature of a liquid?
The boiling temperature of a liquid increases as the gas pressure a the liquid's surface increases.
When a gas is dissolved into a liquid what happens when the pressure increases?
More gas dissolves into the liquid.
Why does a syringe plunger go back in if you pull it out?
When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
Why does the height of the column in a barometer changes as atmospheric pressure changes?
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
Does the boiling point of a liquid decreases increases or stay the same if the intermolecular force increases?
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
Does Increasing the pressure of a liquid lower its boiling point?
The boiling point of a liquid increases when atmospheric pressure is increased.
Can pressure affect the solubility of a substances in a solution?
Pressure can affect the solubility but the effect is not important.
How does pressure exerted by a liquid increase with depth?
It increases linearly, assuming the liquid is incompressible.
What is the pressure inside the bubbles of a boiling liquid?
Vapor pressure
What is the relationship between liquid pressure and depth of a liquid?
As the depth of the fluid increases, the pressure increases. To explain this mathematicaly you consider the Sg of the fluid times the height of the column multiplied by gravity will give you the pressure at the base of the column
Why does density of liquid increases with increasing depth?
Density of a liquid increases with increasing depth because it is being compressed between the weight of matter above it's self and whatever is retaining it. Mass per unit volume (density) increases through only two ways condensing or abating heat.
