# Quick Answer: Is Liquid Compressible Or Not?

## Is a liquid compressible?

The volume of a quantity of liquid is fixed by its temperature and pressure.

Liquids generally expand when heated, and contract when cooled.

On the other hand, liquids have little compressibility.

Water, for example, will compress by only 46.4 parts per million for every unit increase in atmospheric pressure (bar)..

## Why is liquid not compressible?

Because the particles can move, liquids don’t have a definite shape, and they can flow. Because the particles are still packed close together, liquids can’t easily be compressed and keep the same volume.

## Is liquid or solid more compressible?

If we put pressure on a solid or a liquid, there is essentially no change in volume. … The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.

## What is compressibility of liquid?

In thermodynamics and fluid mechanics, compressibility (also known as the coefficient of compressibility or isothermal compressibility) is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
