Chemistry
- answer-The study of substances in terms of composition, structure, properties, and
reactions
Experiment
- answer-A well-defined, controlled procedure for obtaining information about a system
under study
Hypothesis
- answer-A tentative explanation or model for observed natural occurrences
Fact
- answer-A valid observation about some natural phenomenon
Law
- answer-A generalization that concisely summarizes facts about natural phenomena
Physical Change
- answer-A process that does not alter the basic nature (chemical composition) of the
substance undergoing change.
No new substances are ever formed as a result of a physical change
Includes changes of state
Chemical Change
- answer-A process that involves a change in the chemical composition of the
substance
Matter
- answer-The material that makes up all things
Anything that has mass and occupies space

, A single uncontaminated type of matter
ex. pure water
Element
- answer-Composed of one type of atom
Simplest known substance
Pure substances that cannot be separated into simpler substances by ordinary
laboratory processes
building blocks of matter
Compound
- answer-Composed of two or more elements combined in the same portion
Chemically combined elements
Mixtures
- answer-Two or more substances that are physically mixed, not chemically combined
Two or more substances in different proportions
Substances that can be separated by physical methods
Homogenous Mixture
- answer-Composition is uniform throughout the sample
Different parts of the mixture are not visible
ex. tea, milk
Heterogenous Mixture
- answer-The composition varies from one part of the mixture to another
The different parts of the mixture are visible
ex. oil & water/vinegar
