Matter Vocabulary • Matter – anything that has mass and occupies space. • Solids – a state of matter that has a definite volume and a definite shape. • Liquids – a state of matter that has no definite shape but a definite volume. • Fluid - any substance that can flow. • Viscosity – the resistance of a liquid to flowing. • Gases – a state of matter with no definite shape nor volume. • Characteristic properties – a quality of a substance that never changes and can be used to identify the substance. • Melting – the change in state from a solid to a liquid • Melting point – the temperature at which a substance changes from a solid to a liquid, • Freezing – the change in state from a liquid to a solid. • Freezing point – the temperature at which a substance changes from a liquid to a solid. • Vaporization – the change in state from a liquid to a gas. • Evaporation – the process that occurs when vaporization takes place only on the surface of a liquid.
Boiling – the process that occurs when vaporization takes place inside a liquid as well as on the surface. • Boiling point – the temperature at which a substance changes from a liquid to a gas. • Condensation – the change in state from a gas to a liquid. • Sublimation – the change in state from a solid directly to a gas without going through the liquid state.
