phenomena that is always the same under the same conditions
theory - correct answer unifying principle that explains a body of facts and/or those laws based
that are based on them
chemistry - correct answer study of matter and the changes it undergoes
substance - correct answer matter that has a definite or constant composition and distinct
properties
mixture - correct answer combination of two or more substances in which the substances
retain their distinct identities
homogeneous mixture - correct answer composition of the mixture is the same throughout the
solution, after sufficient stirring
heterogeneous mixture - correct answer composition of mixture is not uniform
, element - correct answer substance that cannot be separated into simpler substances by
chemical means
compound - correct answer a substanec composed of two or more elements chemically united
in fixed proportions
extensive property - correct answer depends on how much matter is being considered
intensive - correct answer does not depend on the amount of matter being considered
weight - correct answer force that gravity exerts on an object
