1. elements or compounds Pure substances can either be
_________.
2. compound A substance made up of two or more
different elements chemically bonded
together is called a________
3. homogeneous mixture; homogeneous A ________ is a mixture whose
composition is uniform throughout
the mixture. The salt water de-
scribed above is ________ because
the dissolved salt is evenly distributed
throughout the entire salt water sam-
ple.
4. heterogeneous mixture A ______ is a mixture in which the
composition is not uniform throughout
the mixture. (think vegetable soup)
5. phase/phase Homogeneous mixtures exist in a sin-
gle ____ or layer as they have uniform
composition throughout. Salt water will
have a single _____.
6. Heterogeneous _________ mixtures have two or more
phases as they do not have uniform
composition. For example, oil and wa-
ter do not mix well and separate into
two phases.
7. alloy An _____ is a mixture composed of two
or more elements, at least one of which
is a metal.

pulsive forces that occur between the
molecules in a substance.
16. definite shape (rigid) Solids are defined by the following
definite volume characteristics:
