chemical symbol a one- or two-letter representation of an element
compound a substance that contains two or more elements chemically combined in a fixed proportion
distillation a process used to separate dissolved solids from a liquid, which is boiled to produce a vapor that is then condensed into a liquid
element the simplest form of matter that has a unique set of properties; an element cannot be broken down into simpler subtsances by chemical means
extensive property a property that depends on the amount of matter in a sample
filtration a process that separates a solid from the liquid in a heterogeneous mixture
gas a form of matter that takes the shape and volume of its container; a gas has no definite shape or volume
heterogeneous mixture a mixture that is not uniform in composition; components are not evenly distributed throughout the mixture
homogeneous mixture a mixture that is uniform in composition; components are evenly distributed and not easily distinguished
intensive property a property that depends on the type of matter in a sample, not the amount of matter
law of conservation of mass in any physical change or chemical reaction, mass is conserved; mass can be neither created nor destroyed
liquid a form of matter that flows, has a fixed volume, and an indefinite shape
mass a measure of the amount of matter that an object contains; the SI base unit of mass is the kilogram
mixture a physical blend of two or more substances that are not chemically combined

physical property a quality or condition of a substance that can be observed or measured without changing the substance's composition
precipitate a solid that forms and settles out of a liquid mixture
product a substance produced in a chemical reaction
reactant a substance present at the start of a reaction
solid a form of matter that has a definite shape and volume
solution a homogeneous mixture; consists of solutes dissolved in a solvent
substance matter that has a uniform and definite composition; either an element or a compound; also called pure substance
vapor describes the gaseous state of a substance that is generally a liquid or solid at room temperature
volume a measure of the space occupied by a sample of matter
