What is liquid? Liquid State of Matter

What is liquid? A liquid is a nearly incompressible fluid that adapts to its container’s shape while maintaining a (nearly) fixed volume regardless of pressure. It is thus one of the four basic states of matter (the others being solid, gas, and plasma) and the only one having a definite volume but no fixed shape. A liquid is made up of small vibrating matter components, such as atoms, that are bound together by inter-molecular connections.

A liquid, like a gas, can flow and acquire the shape of a vessel. Although most liquids are resistant to compression, others can be compressed. A liquid, unlike a gas, does not disperse to cover all of the spaces in a container and maintains a relatively constant density. Surface tension is a characteristic of the liquid state that causes wetting phenomena. Water is the primary liquid on the planet.

A liquid’s density is usually close to that of a solid and significantly higher than that of a gas. Be a result, both liquid and solid are referred to as crystalline materials. Liquids and gases, on the other hand, are both referred to as fluids since they have the potential to flow. Although liquid water is ubiquitous on Earth, it is the least frequent form of matter in the known universe due to the fact that liquids require a relatively limited temperature/pressure range to exist. The majority of known stuff in the cosmos is in the form of gaseous interstellar clouds or plasma from within stars (with remnants of visible solid matter).
