States of Matter How Do We Classify Them? ØBased upon particle arrangement ØBased upon energy of particles ØBased upon distance between particles 3
States of Matter Solids §Particles of solids are tightly packed, vibrating about a fixed position. §Solids have a definite* shape and a definite* volume. 4
States of Matter Definite Means It does not change based on its container Example: Put a sneaker in a box. It stays the same. • 5

States of Matter Liquids §Particles of liquids are tightly packed, but are far enough apart to slide over one another. §Liquids have an indefinite* shape and a definite volume. 7
States of Matter • Indefinite Means It changes based on its container Example: The same amount of liquid will have a different shape if it is poured into a skinny test tube or a short round Petri dish 8

States of Matter Gases §Particles of gases are very far apart and move freely. §Gases have an indefinite shape and an indefinite volume. 10
