How will a person feel liquid pressure as she goes at different depths in a swimming pool?

the deeper she goes there is more weight above her thus greater pressure which results to pain in the eardrums

Why is the outer core is a liquid?
The outer core of the earth, composed primarily of iron and nickel, remains liquid because pressure at those respective depths is not sufficient to prevent a phase change from solid to liquid. The inner core remains solid because pressure at those depths prevents any expansion in volume, which is necessary for a substance to be in a liquid state.
Where is fluid pressure greatest?
at the ocean and going deeper into it
What is the boiling point of a liquid at a pressure of 101.3 kPa?
Each liquid has a different boiling point; 101,3 kPa is he standard atmosphere pressure (atm).
How will show that the process of evaporation depends on the nature of the liquid?
By the measurement of the pressure vapour at a given temperature; this value is different from liquid to liquid.
Why atmospheric pressure varies with height in a different way from the way liquid pressure varies with depth.?
For the same reason. The liquid above the location considered, or the atmosphere above the position considered, helps contribute to the pressure; if there is more liquid or atmosphere above, there is more pressure.
How can you tell if the object will sink or float in a liquid?
Depends on the liquid, different liquids have different densities thus different things will float or sink in them. If it's water you're try throwing the object in a swimming pool.
What are the Laws of liquid pressure?
1) Pressure increases with depth 2) Pressure is the same on the same horizontal plane of the liquid 3) Pressure varies with different liquids on the same horizontal plane 4) Pressure is the same in all directions about a point 5) A liquid seeks its own level
Why do you think water from the different holes have different trajectories?
the trajectory of water is used as indicator of pressure. The longer the trajectory, the greater is the pressure at that point of the liquid column. Water pressure at any point in a closed container is dependent on the height of the liquid above it.
What makes mercury different from metal?
It is in its liquid phase at standard temperature and pressure.
Will you drown from swimming in beer?
You can drown swimming in any liquid if you are not careful.
What makes Mercury different from most metals?
It is in its liquid phase at standard temperature and pressure.
What is in liquid?
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.
