what is fluid and what is the use of fluid
Answers
Answer:
In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress, or external force.Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them.
Answer:
Fluids display properties such as:
Fluids display properties such as:not resisting permanent deformation, resisting only relative rates of deformation in a dissipative, frictional manner, and
Fluids display properties such as:not resisting permanent deformation, resisting only relative rates of deformation in a dissipative, frictional manner, andthe ability to flow (also described as the ability to take on the shape of the container).
Fluids display properties such as:not resisting permanent deformation, resisting only relative rates of deformation in a dissipative, frictional manner, andthe ability to flow (also described as the ability to take on the shape of the container).These properties are typically a function of their inability to support a shear stress in static equilibrium. In contrast, solids respond to shear either with a spring-like restoring force, which means that deformations are reversible, or they require a certain initial stress before they deform (see plasticity).

In contrast, solids respond to shear either with a spring-like restoring force, which means that deformations are reversible, or they require a certain initial stress before they deform (see plasticity).Solids respond with restoring forces to both shear stresses and to normal stresses—both compressive and tensile. In contrast, ideal fluids only respond with restoring forces to normal stresses, called pressure: fluids can be subjected to both compressive stress, corresponding to positive pressure, and to tensile stress, corresponding to negative pressure. Both solids and liquids also have tensile strengths, which when exceeded in solids makes irreversible deformation and fracture, and in liquids causes the onset of cavitation.

Both solids and liquids also have tensile strengths, which when exceeded in solids makes irreversible deformation and fracture, and in liquids causes the onset of cavitation.Both solids and liquids have free surfaces, which cost some amount of free energy to form. In the case of solids, the amount of free energy to form a given unit of surface area is called surface energy, whereas for liquids the same quantity is called surface tension. The ability of liquids to flow results in different behaviour in response to surface tension than in solids, although in equilibrium both will try to minimise their surface energy: liquids tend to form rounded droplets, whereas pure solids tend to form crystals. Gases do not have free surfaces, and freely diffuse.
