What is Matter? Atoms bonded together make molecules
Matter in Motion Molecules are constantly moving Temperature is a measure of this movement
Changes in Matter Physical Chemical Solid Liquid Gas Phase Changes (Melting, Boiling, Sublimation) Chemical Atoms rearranged to form new substances Solid Liquid Gas 2C3H8 + 10O2 → 6CO2 + 8H2O
Density of Matter Mass per volume Less dense materials float in more dense materials
