Liquid

Definition

A liquid is a state of matter characterized by a definite volume but no fixed shape, conforming to the shape of its container. It has particles that are close together but can move past each other, allowing for fluidity.

5 Must Know Facts For Your Next Test

1. Liquids have a definite volume but take the shape of their container.
2. The particles in a liquid are close together with no regular arrangement, allowing them to flow.
3. Surface tension and viscosity are key properties of liquids.
4. Liquids exhibit minimal compressibility compared to gases.
5. Phase transitions involving liquids include melting (solid to liquid) and boiling (liquid to gas).

Related terms

Solid:

A state of matter characterized by a fixed shape and volume, with closely packed particles in a structured arrangement.

Gas:

A state of matter without a definite shape or volume, consisting of particles that are far apart and move freely.

Viscosity:

A measure of a fluid's resistance to flow; higher viscosity means thicker fluid.
