Question

Liquid exert pressure in all directions.
$\left( a \right){\text{ True}}$
$\left( b \right){\text{ False}}$

Answer 1

Hint So to answer this question whether it is true or false, we should know first the properties of the fluids or liquids. As we know molecules present in the liquids or fluids are closely packed and there will be a distance between them. So by using these points in mind we can easily answer.

Complete Step By Step Solution Liquids don't have any specific shape and so every molecule in the liquid wants to be in a low energy state which is achieved when it lies flat on any surface with the gravity acting perpendicularly and so when you place the liquid in a container then the liquid tries to go in low energy state and hence exerts pressure on the sides on the container to lay flat and thereby exerts pressure in all directions.
Due to being closely packed the distance between them helps in moving the upward, downward, or in any direction. And in this way the movement of molecules exerts pressure. We also know that the liquid does not have faces and nor do they have rigidity. The only property it has is the property to flow. For example- when we flow the water in-floor it goes in all directions we can't say that it goes only in one direction it can go in one direction only when we make a boundary near it.
Hence the statement is true.

Note The pressure in fluid increments with profundity. The pressure of water is most noteworthy at the absolute bottom of the chamber as the water sprays out the uttermost starting here. The pressure in a fluid doesn't rely upon the shape or size of the holder. The pressure in a fluid demonstrates toward all path pressure applied in straightforwardly identified with its thickness.
