• noun A substance whose parts change their relative position on the slightest pressure, and therefore retain no definite form; any substance in the state of liquidity; a fluid that is not gaseous and has a definite volume independent, of the container in which it is held. Liquids have a fixed volume at any given pressure, but their shape is determined by the container in which it is contained. Liquids, in contrast to gases, cannot expand indefinitely to fill an expanding container, and are only slightly compressible by application of pressure.

• noun a measure, or system of measuring, for liquids, by the gallon, quart, pint, gill, etc.
