As the height of liquid in a column increases, the amount of pressure will be:
(a) Less
(b) More
(c) No change
(d) None of the above
Answers
As the height of liquid in a column increases, the amount of pressure will increase at various depths, but on the surface.
Explanation:
The height of liquid in a column doesn't affect the pressure on the surface of the water. The pressure on the surface corresponds to the atmospheric pressure above it.
However, the pressure in a liquid is affected only by the weight of the liquid above it. So at various depths of the liquid column, the weight of the liquid above it will change with the height of liquid in a column increases. Thereby, the pressure at various depths will proportionately increase when the height of the liquid column increases.
As the height of the liquid in a column increases, the amount of pressure will be more.
Explanation:
The correct answer to this question is option b, More.
It is to be noted that the overall pressure exerted by a specific amount of water keeps on increasing with its increasing depth.
In other words, with every increase in height, the pressure will also increase at a gradual rate.
