What is Fluid?
Fluids is a substance that cannot resist a shear force or stress without moving as can a solid. It is usually classified as liquids or gases. A liquid has intermolecular forces that hold it together so that it possesses volume but no definite shape.

What is Liquid?
The liquid state lies between the gaseous and the solid-state in the sense that there is neither the ordered arrangement of constituents nor the complete disorder as in gases.
Due to the common usage of the term fluid in many instances, it 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 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 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 a few things. You can check them out below.

|---|---|
| Fluid | Liquid |
| Fluid is a common state of certain substances, or a type of matter. | Liquid is one of the three phases or states of matter. |
| Fluids flow and have some viscosity (thickness). | Liquids also flow and it has volume but no definite shape. |
| Fluids come along for 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. |

Frequently Asked Questions – FAQs
Is water a fluid or liquid?
Water is the most abundant substance on Earth, by far. The liquid density is typically similar to that of a solid, and far greater than that of a gas. So both liquid and solid are considered condensed matter. On the other hand, these are considered fluids because liquids and gases have the capacity to flow.
What is fluid explain types of fluid?
Fluid flow has all sorts of characteristics, whether smooth or turbulent, compressible or incompressible, viscous or non-viscous, and, to name a few, rotational or irrotational. Several of these characteristics illustrate the liquid ‘s properties themselves and some rely on how the fluid flows.
Why is liquid incompressible?
Liquids are commonly called incompressible. The molecules are too similar together, so they can hardly be squeezed any further. Liquids can potentially compress under extremely high pressures but not too much. Unlike fuels, liquids have a clear surface they don’t need to assume the shape of their bottle.
What is the most compressible liquid?
Mercury is the most compressible, instantly. A cube of volume Vc and density πc is put in a cylindrical container in some liquid and partially submerged floats, creating a difference in the liquid ‘s height.
What is fluid and its properties?
Fluid properties (three types) Kinematic properties-fluid motion-related properties, such as velocity and acceleration. Thermodynamic properties-the properties that characterise a fluid’s thermodynamic condition. Temperature, heat, density, internal energy, basic entropy, precise enthalpy, etc.
