6. Vocabulary
• Physical property: a property that describes a substance by itself, such as color, shape, density, or
hardness.
• Mass: the amount of matter something has.
• Volume: the amount of space something takes up.
• Density: the amount of mass something has in relation to its volume.
• Physical change: a change that does not make a substance into a new substance.
• Mixture: a combination of two or more substances that keep their original properties.
• Solution: a mixture in which all of the substances are evenly distributed.
• Suspension: a mixture that contains particles that are large enough to be seen.
• Colloid: a mixture that contains particles that are too small to see.
• Chemical change: a change in which one or more new substances are formed.
• Chemical property: a property that involves the ability of a substance to react with other materials
and form new substances.
• Reactivity: the ability of a substance to go through a chemical change.
• Stability: the ability of a substance to resist going through a chemical change.
• Acid: a substance that turns blue litmus paper red.
• Base: a substance that turns red litmus paper blue.
• Indicator: a material that indicates whether a substance is an acid or a base.
• pH scale: a measure of the strength or weakness of acids and bases.

14. Dissolving, Melting, and Boiling
• The ability of a substance to dissolve is a physical property.. the
term for this property is solubility, a measure of how much of a
substance will dissolve in a liquid.
• Glass is a solid when it is cold. When you apply enough heat it
softens and becomes a liquid. This property is based on melting or
the change from solid to liquid.
• Boiling is the change from a liquid form to a gas form.

24. Chemical Properties and Changes
• When a substance goes through a physical change, the substance
itself is not changed.
• A chemical change is a change in which one or more new
substances are formed.
• One way to observe if a chemical reaction has happened is to
observe for new chemical properties. A chemical property is
something that describes the ability of a substance to react with
other materials and form new substances.
• Reactivity is the ability of a substance to go through a chemical
change.
• The opposite of reactivity is stability. Stability is the ability of a
substance to resist going through a chemical change.
