Difference Between Fluid and Liquid

Due to the common usage of the term fluid in many instances it often often creates an impression that it is a synonym for liquid. For example, we might have been advised by our doctors saying, “drink more fluids”. In another instance, when you are studying chemistry you will often come across “water is a liquid.” While fluid and liquid sound very similar and if you have been wondering if they are the same thing or not then we have an answer for you. They are totally different terms and there are few differences between the two.

When we talk about fluids, it is nothing but a substance that that flows and it consists of both gases and liquids. Whereas a liquid is defined as a substance having rigidity and it mostly occupies the shape of any vessel it is placed in. Besides, knowing the difference between fluid and liquid is important to understand how matter works.

Difference Between Fluid and Liquid

It is also worth mentioning that liquids are fluids but not all fluids are liquids. It is mainly because fluids also comprise of substances in a gaseous phase. To give you an example, Nitrogen gas is a fluid, whereas a mango juice is both a fluid and a liquid. However, the difference between fluid and liquid boils down to few things. You can check them out below.

Difference Between Fluid and Liquid

Fluid

Liquid

Fluid is a condition specific to certain substances or it is a subset of matter.

Liquid is one of the three phases or state of matter.

Fluids flow and has some viscosity (thickness).

Liquids also flows and it has volume, but no definite shape.

Fluids include liquids.

All liquids are fluid.

A fluid is a substance that lacks rigidity it cannot resist force when it is applied to it.

Liquids can assume the shape of any container or vessel and they are relatively incompressible.

These are some of the differences between fluid and liquid. To know more about important differences between other chemistry topics you can keep visiting BYJU’s or download our app for interesting content and learning experience.
