liquid - Students | Britannica Kids | Homework Help
WEBLiquid is one of the three principle states of matter. In its characteristics, a liquid is intermediate between a gas and a solid, the other two principle states. Like gases, liquids can flow and take on the shape of the container in which they are placed—characteristics not found in solids.
Liquid - Molecular Structure, Intermolecular Forces, Viscosity
WEBSep 26, 2024 · Liquids possess neither the completely ordered structure of a solid crystal nor the complete randomness of an ideal gas. The structure in a liquid is intermediate to these two extremes—i.e., the molecules in a liquid are free to move about, but there is some order because they remain relatively close to one another.
