States of matter

  1. 1. States of Matter
  2. 2. There are three phases of matter on Earth : Little space between molecules and can only vibrate Have a definite SHAPE Have a definite VOLUME
  3. 3. 2) : Molecules are loosely bonded (can flow past each other) definite (can take the shape of the container) a definite (liquid levels off)
  4. 4. 3) : Lots of space between molecules (particles move freely and collide often) definite definite (molecules spread to all areas of the container)
  5. 5. • Both and can affect the phase of matter. • Lower temperature means less movement equals solid
  6. 6. • Increased pressure on a gas can force gas into a liquid.
  7. 7. Change in • During a change of state, particles in a substance OR they begin to move
  8. 8. Change of State Solid -> Liquid Melting (add heat) Liquid -> Solid Freezing, Crystallization, Congealing (remove heat) Liquid -> Gas Evaporation (add heat) Gas -> Liquid Condensation (remove heat) Solid -> Gas Sublimation (no liquid phase) (add heat) Gas -> Solid Resublimation (no liquid phase) (remove heat)
  9. 9. • From a solid or a liquid to a gas • Energy must be absorbed to vaporize a solid or a liquid
