2. Chapter 1~ Introduction to Chemistry Chapter 2~ Analyzing Data
Is the study of the composition, structure, and properties of matter and changes it undergoes.
Substance: is a matter that has a definite and uniform
composition.
Chemical: any substance that has a defined composition.
Chemical Reaction:
the process by which one or more substances change to produce one or more substances.

3. the physical forms of matter, which are solid, liquid, gas and plasma.
States of Matter:
the physical forms of matter, which are solid, liquid, gas and plasma.
Reactant:
a substance or molecule that participates in a chemical reaction.
Product: a substance that forms in a chemical reaction.
Matter: anything that has mass and takes up space; “stuff”.
Volume:
a measure of the size of a body or region in three dimensional space.
Mass : a measure of the amount of matter in an object.
weight = mass * gravity
