Concept

Key idea

Matter has mass and takes up space. Three common states are solid, liquid, and gas. A solid, such as an ice cube, normally keeps its own shape and volume. A liquid, such as water, keeps its volume but takes the shape of the part of a container it occupies. A gas, such as air, spreads to fill the available space. Matter is made of tiny particles. In a solid, particles vibrate around fixed positions; they are not motionless. In a liquid, nearby particles can move past one another. In a gas, particles are much farther apart and move in different directions. The spaces between gas particles make gases easier to compress than solids or liquids. A material's state does not tell us every property. Clear glass is a transparent solid, and clear water is a transparent liquid. Milk is a liquid that we cannot see clearly through. Solubility describes how much of a substance can dissolve in a particular liquid at a given temperature.
