Chemical change
A. A change of matter from one form into
another without a change in chemical
properties.
B. A change that occurs when one or more
substances change into entirely new
substances with different properties.
C. A characteristic of a substance that does
not involve a chemical change.
D. A property of matter that describes a
substance’s ability to participate in
chemical reactions.
E. A property that is always the same, no
matter what size the sample is which
makes it useful for identifying a
substance.
F. The ability of a substance to be pulled
into a wire.
G. The ability of a substance to be rolled or
pounded into thin sheets.

combine and form one or more new
substances.
K. The mass per unit volume of a substance.
L. The physical form in which a substance
exists, such as solid, liquid, or gas.
