Question

If the density of a liquid increases, the pressure at a point inside the liquid at a given depth:

• A. decreases
• B. remains same
• C. increases
• D. sometimes decreases and some time increases

Answer 1

Answer: (C)

increases

The expression of the pressure at a point in fluid is given by $P=h\rho g$

where $h=$ depth of the point from the surface, $\rho =$ be the density of the fluid and $g=$ acceleration due to gravity.

Thus, the pressure in liquid is proportional to the density of the liquid.

So when density increases, the pressure at a point in the liquid will be increasing.
