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.

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 factors affect hydrostatic pressure?
depth of liquid and density of the liquid
The pressure at the bottom of a barrel filled with liquid does NOT depend on the?
liquid density
Pressure on the surface of liquid depends on?
The depth of the measuring point and the density of the liquid
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.
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 :)

liquid density
What is the difference between liquid pressure and depth?
Liquid pressure depends on depth. It can be calculated from liquid density times depth.
Pressure on the surface of liquid depends on?
The depth of the measuring point and the density of the liquid
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.
Is the density of gas similar to that of a liquid?
No, a pure liquid at normal temperature has a constant density while the density of a gas depends upon temperature and pressure.
How does upward pressure find?
pressure =force/ area pressure of a liquid is density time height.
What is the relationship between liquid depth and pressure?
the pressure of liquid is HDG where H=depth D=density g= acceleration due to gravity thus depth= pressure/density*acceleration due to gravity
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.
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
