Unit 1: Foundations of Matter Density:
Density means how
concentrated or
Physical Properties: Examples: compact
Can be observed or something is.
measured without
changing the composition Density Equation:
of the substance.
Chemical Properties:
Chances substances
chemical identity.
Physical and Chemical Examples:
Changes can be Water boiling = physical change
evaluated and because boiling point is a physical
determined through property
physical and chemical Wood burning = chemical change
properties. because flammability is a chemical
change.
Percent Error:
This equation shows the percentage of
how how inaccurate something is.
Types of Matter:
Atoms: basic unit of
matter
Element: one type of Atoms, Elements, and
atom Compounds are all pure
Compound: two or more substances!
chemically combined
elements Heterogeneous mixtures ARE
Mixture: 2 or more NOT evenly mixed, while
substances Homogenous ARE evenly mixed!
