Liquid

State of matter The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids. Liquid is a state of matter with a definite volume but no fixed shape. When confined in a container and subject to a force such as gravity, liquids will adapt to the internal shape of the container in the direction of the force. Liquids are nearly incompressible, maintaining their volume even under pressure. The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Liquids are a form of condensed matter alongside solids, and a form of fluid alongside gases. A liquid is composed of atoms or molecules held together by intermolecular bonds of intermediate strength. These forces allow the particles to move around one another while remaining closely packed. In contrast, solids have particles that are tightly bound by strong intermolecular forces, limiting their movement to small vibrations in fixed positions. Gases, on the other hand, consist of widely spaced, freely moving particles with only weak intermolecular forces. As temperature increases, the molecules in a liquid vibrate more intensely,
