What are Physical Properties of Matter? Properties that a substance displays without changing its composition.
What are examples of Physical Properties of Matter? Odor, taste, color, appearance, melting point, boiling point, and density.
What are Chemical Properties of Matter? Properties that a substance displays only by changing its composition via a
chemical change.
What are examples of Chemical Properties of Matter? Corrosiveness, flammability, acidity, toxicity, and other such characteristics.
What are Physical Changes in Matter? Changes that alter only state or appearance, but not composition. These are
easily reversable.
What is an example of a physical change in matter? When water boils, its state is changed from a liquid to a gas, but the gas is still
made of water molecules, so the chemical identity (composition) is not
changed.
What are Chemical Changes in Matter? Changes that alter the composition of matter. These require chemical reactions
to reverse them.

What is an example of a chemical change in matter? When iron rusts, the iron atoms combine with oxygen atoms to form a different
chemical substance, the compound iron oxide, so its chemical identity
(composition) is changed.
What three compositions can Matter be classified by? Elements, Compounds, Mixtures
What is a pure substance? Something made up of only one component, and its composition is invariant (it
does not vary from one sample to another).
What are examples of pure substances? Helium, water, and sodium chloride; helium is made up of ONLY helium atoms,
water is made up of ONLY water molecules, and sodium chloride is made up
ONLY of sodium chloride units.
What is a mixture? Something composed of two or more components in proportions that can vary
from one sample to another.
What is an example of a mixture? Sweetened tea, composed primarily of BOTH water molecules and sugar
molecules; it is not made up ONLY of one or the other.
Pure substances can be classified into what two types? Elements, Compounds

What is an element? A substance that cannot be chemically broken down into simpler substances
(composed of a single type of atom, like Helium).
What is a compound? A substance composed of two or more elements in a fixed, definite proportion,
like hydrogen and oxygen comprising water.
Mixtures can be categorized into what two types? Heterogeneous, Homogeneous
What does it mean if a mixture is heterogeneous? The composition varies from one region of the mixture to another, like different
letters spread out in an alphabet soup; there are multiple substances whose
presence can be seen.
What does it mean if a mixture is homogeneous? The composition stays the same (uniform) throughout all regions of the mixture,
like how sweet tea should taste the same throughout a whole glass; made of
multiple substances but appears to be one substance.
What are qualitative observations? Observations that are descriptive in nature, not involving numbers.
What are quantitative observations? Observations that involve measurements (numbers).
