Imagine three glass tubes with equal cross-section of 1 square cm and of length 100 cm each. Fill the first tube with water to the 75cm mark, the second to the 50cm mark and the third to the 25cm mark. The density of water would be one of the following
1) Mass of the 75cm column with a cross section of 1 sq cm divided by 75 cubic cm
2) Mass of the 50cm column with a cross section of 1 sq cm divided by 50 cubic cm
3) Mass of the 25cm column with a cross section of 1 sq cm divided by 25 cubic cm
and in each case should give you an answer close to 1 gm per cubic cm. Thus the density stays the same no matter how high the water is in each tube.
On the other hand the pressure at the bottom of each tube is different and is the force exerted per unit area by the column of water in each tube which are again different. We have conveniently selected tubes with 1 sq cm (unit area in CGS system) cross sectional areas. So the weight of the column in each tube would be the pressure. Hence the pressure in the first tube would be
1) Weight of the 75cm water column = 75 x 1 x g = 75g dynes
2) Weight of the 50cm water column = 50 x 1 x g = 50g dynes
3) Weight of the 25cm water column = 25 x 1 x g = 25g dynes
Thus density remains the same for a given temperature and pressure but the pressure depends on the weight the column of liquid per unit area.

Pressure on the surface of liquid depends on?
The pressure on the surface of a liquid depends on the depth of the liquid and the density of the liquid. The pressure increases with depth due to the weight of the liquid above and also depends on the density of the liquid.
Relationship between liquid pressure and density?
If you were submerged in a liquid more dense than water, the pressure would be correspondingly greater. The pressure due to a liquid is precisely equal to the product of weight density and depth. liquid pressure = weight density x depth. also the pressure a liquid exerts against the sides and bottom of a container depends on the density and the depth of the liquid.
What are the factors on which liquid pressure depends?
Liquid pressure depends on the depth of the liquid, the density of the liquid, and the gravitational acceleration acting on the liquid. The pressure increases with depth due to the weight of the liquid above and is directly proportional to the density of the liquid.
Upon what factors does liquid pressure depend?
Atmospheric pressure Density of the liquid Gravitional field strength in the area the liquid is in The distance from the surface of the liquid i.e. depth Pressure in a liquid=Atmospheric pressure +(Depth X Gravity strength X Density) There might be more I don't know about
The pressure at the bottom of a barrel filled with liquid does NOT depend on the?
The pressure at the bottom of a barrel filled with liquid does not depend on the shape or size of the barrel. It depends only on the depth of the liquid and the density of the liquid.
What is the relationship between liquid pressure and the depth of a liquid between liquid pressure and density?
pressure of liquid on bottom=density*gravitational force*depth :)

If you are submerged in a liquid denser than water what will happen to the pressure?
The pressure will get higher quicker than in water because there is a different density between the liquids, and because there is a higher density, the liquid will be heavier and would push on you more than the smaller density of water. if you would submerge deep in that liquid, you will explode at a lower distance from the surface than in water.
The pressure at the bottom of a barrel filled with liquid does NOT depend on the?
The pressure at the bottom of a barrel filled with liquid does not depend on the shape or size of the barrel. It depends only on the depth of the liquid and the density of the liquid.
How does the pressure exerted by a liquid change as density of the liquid changes?
The pressure exerted by a liquid increases with the density of the liquid. This is because the weight of the liquid above a certain point increases with higher density, leading to a greater force per unit area or pressure at that point.
What is the difference between liquid pressure and depth?
Liquid pressure depends on depth. It can be calculated from liquid density times depth.
Does the pressure on the bottom of a tank of fluid varies directly with the density of the liquid in the tank?
No, the pressure at the bottom of a tank of fluid is directly proportional to the height of the fluid above that point and the density of the liquid, according to the hydrostatic pressure formula. It is not directly proportional to the density of the liquid alone.
What does not effect the pressure at a point beneath the surface of a liquid?
The shape of the container, the size of the container, and the density of the liquid do not affect the pressure at a point beneath the surface of a liquid. The pressure at a point in a liquid is only dependent on the depth of the point and the density of the liquid above it.
How does the pressure exerted by a liquid vary with direction and depth?
The pressure exerted by a liquid increases with depth. This is known as hydrostatic pressure and is directly proportional to the density of the liquid. The pressure variation with direction is isotropic, meaning it is the same regardless of the direction taken in the liquid.
