# Explain Why Liquids Can Flow But Are Not Compressible

Like a gas a liquid is able to flow and take the shape of a container. Hence the liquids are considered.

### Generally all fluids are compressible and in case of liquids the compress ability is less and hence for solving purposes they are considered to be zero.

Explain why liquids can flow but are not compressible. Liquids have definite volume but not a definite shape. Become a member and. The atoms of any liquid are held so tight that can can just slide over each other.

A flow is said to be incompressible if the variation in its density is very low which can be neglected. Infact you cannot compress them simply because the force of repulsion between the atoms will not. Therefore any increase in one form results in a decrease in the other.

Liquids are said to have low compressibility. They are not tightly packed and fluid obtains the shape of the container which it occupies. One of the most notable properties of liquids is that they are fluid and they can flow.

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a nearly constant volume independent of pressure. At the atomic level fluids are composed of atoms or molecules which flow easily. Most solids and liquids expand with temperature ice is an exception – it contracts with increased temperature because there is more energy in the particles and therefore they move faster and.

The particles do not move enough so they are fixed in place and the liquid has a fixed volume. They arent absolutely incompressible but theyre approximately incompressible for the most part. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.

Technically compression is nothing but. So the small variations in the flow are considered to be zero and the flow is called incompressible. The particles do not move enough to change positions so the liquid is not compressible.

Favorite Answer Liquids can not be compressed because there is only a very small distance between the molecules themselves when they are bonded. Invariably it is true for liquids because the density of liquid decreases slightly with temperature and moderately with pressure over a broad range of operating conditions. The simplest form of Bernoullis equation steady and incompressible flow states that the sum of mechanical energy potential energy and kinetic energy along a streamline is constant.

While all flows are compressible flows are usually treated as being incompressible when the Mach number the ratio of the speed of the flow to the speed of sound is smaller than 03 since the density change due to velocity is about 5 in that case. The solids are highly ordered and are not compressible because the molecules of solids are tightly packed to each other and they can not flow as they. The key difference between compressible and incompressible fluids is that the compressible fluids occur in reality whereas the incompressible fluids is a concept developed for ease of calculations.

The particles move enough that they separate from one another and take the shape of their container. In fluid dynamics the compressibility of a fluid is a very important factor. The main difference between compressible and incompressible fluid is that a force applied to a compressible fluid changes the density of a fluid whereas a force applied to an incompressible.

Fluids are either gases or liquids that take the shape of the container. Compressible flow or gas dynamics is the branch of fluid mechanics that deals with flows having significant changes in fluid density. Also when the variation of density in the flow domain is negligible then the flow can be treated as incompressible.

Liquid In a liquid particles will flow or glide over one another but stay toward the bottom of the container. Bernoullis equation considers only pressure and gravitational forces acting on the fluid particles. Most liquids resist compression although others can be compressed.

Its because liquids are molecules which are practically already in contact but just not. The term compressibility is also used in thermodynamics to describe the deviance in the thermodynamic properties of a real gas from those expected from an ideal gasThe compressibility factor is defined as _ where p is the pressure of the gas T is its temperature and V is its molar volumeIn the case of an ideal gas the compressibility factor Z is equal to unity and the familiar ideal. See full answer below.

Gas In a gas particles are in continual straight-line motion. Gases and liquids called fluids because of their ability to flow ability to deform when a force is applied and high fluidity.
