  1. Phases of Matter What distinguishes the forms of matter?

  2. States of Matter: SOLIDS • Molecules vibrate back and forth. • Particles don’t have theenergy to move around each other. • Does not flow • Rigid structure • Definite volume • Definite shape

  3. States of Matter: LIQUIDS • Particle take the shape of their container. • Particles have enough energy to move around each other. • Definite volume • NO definite shape

  4. States of Matter: GASES • Particles have enough energy to move around freely. • Gases can exert pressure and they are compressible. • Takes the shape and volume of a container. • NO definite volume • NO definite shape States of Matter

  5. States of matter: PLASMA • Most common state of matter in the universe. • Gas-like mixture of particles. • This occurs naturally on the sun and in stars. • NO definite volume • NO definite shape • On earth, plasma can be found in florescent light bulbs.

  6. How does energy change matter? • Matter can change from one form to another by the addition or subtraction of energy. • Solid  melting  Liquid • Liquid  evaporation  Gas • Gas  condensation  Liquid • Liquid  freezing  Solid • Solid  deposition  Gas • Gas  sublimation  Solid

  7. Phase changes: Heating Evaporation Tempera t ure Gas Melting Liquid Solid Time

  8. Phase changes: Cooling Condensation Tempera t ure Gas Freezing Liquid Solid Time
