The question is a bit vague, but two things come into play for pressure in a liquid: external pressure and hydrostatic pressure. For a liquid where the top surface is in contact with a gas, like a glass of water sitting out on the table, the external pressure would be the pressure of the gas. For the glass of water in this example, the pressure of the gas is just the ambient atmospheric pressure. In a pressure cooker with hot gas and hot liquid confined in a fixed volume, the pressure of the gas will probably reach the pressure the relief valve is set to. Hydrostatic pressure comes from the weight of the liquid above the liquid at any point in the liquid. As an example, if you go 10 meters down under the surface of the water in a swimming pool, you will feel the pressure created by the weight of the water above you. As a formula, P.H. (hydrostatic pressure) = (gravitational acceleration)x(density of liquid)x(depth of liquid). To get total pressure at any point in a liquid, you add the external pressure and the hydrostatic pressure. In situations like a hydraulic line, you would add the pressure exerted by the piston (external pressure) to the hydrostatic pressure from changes in the height of the hydraulic line. By the way, if the line goes UP, the effective depth is NEGATIVE and the hydrostatic pressure term is also negative, so you would have less pressure at the top of the hydraulic line than you did down at the level of the piston.
What else can I help you with?
Are there liquids on Mars?
No, it doesn't have enough atmospheric pressure to support liquids.
What are devices whose operations depends on pressure of liquids?
Some devices that operate based on the pressure of liquids include hydraulic systems for machinery, pressure sensors for measuring fluid levels, and pressure relief valves for controlling the flow of liquids in pipelines.
Does increases in pressure increase the compressibility of liquids?
No, increases in pressure do not increase the compressibility of liquids. Liquids are considered to be nearly incompressible under most conditions, meaning their volume does not change significantly with changes in pressure.
When is boiling point?
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
What The study of pressure on liquids?
The study of liquids at rest called is known as hydrostatics. This a study of the mechanism of fluids which is a branch of physics.
What is the relationship between pressure and volume in liquids.Pressure is directly proportional to the volume. If the volume is greater the pressure also will be greater in liquids. Is it correct?
Not quite. In liquids, the relationship between pressure and volume is not as simple as in gases, where there is a direct proportionality. In liquids, the relationship between pressure and volume is influenced by factors such as density and temperature, in addition to volume. So, it is not accurate to say that pressure is directly proportional to volume in liquids.
What kind of solution is affected by pressure?
At higher pressure the dissolution of gases in liquids is increased.
What is a device that uses liquids to transmit pressure?
Hydraulics

Yes
Why liquids exert pressure on the walls of a container?
To expand
Which fundamental force contributes to pressure both in pressure and atmosphere?
gravity
How does pressure affect the solubility of gases in liquids?
Increasing pressure typically increases the solubility of gases in liquids because the gas molecules are forced into the liquid by the higher pressure. This is described by Henry's Law, which states that the solubility of a gas is directly proportional to the partial pressure of that gas above the liquid. Conversely, decreasing pressure tends to decrease the solubility of gases in liquids as the gas molecules can escape from the liquid more easily.
