Question

Fluids exert pressure on

• A. Air
• B. The container in which they are stored
• C. Both A and B
• D. Their own molecules which are present on the surface of the container

Answer 1

The correct option is B

The container in which they are stored

A fluid is a substance that has no fixed shape and yields easily to external pressure; a gas or a liquid.

Pressure is exerted by fluids because of their weight.

Static fluid pressure is given as = $\rho \times g\times h$

where $h$ = depth of the fluid,

$\rho$ = the density of the fluid and

$g$ = the acceleration of gravity.

Hence they exert pressure in the container in which they are stored.
