  1. Fill in the Chart

  2. Think About It • What happens to a puddle of water on a sunny day? • What happens to ice on a warm day? • What happens to a pond in very cold temperatures?

  3. Changes of States

  4. Changes between Solids & Liquids Melting: change in state from a solid to a liquid • Melting occurs at a specific temperature called, melting point • A change from a solid to a liquid involves an increase in thermal energy

  5. Changes between Solids & Liquids Freezing is the change of state from liquid to a solid • A change from a liquid to a solid is a decrease in thermal energy

  6. Brain Break

  7. Changes between Liquid & Gas Vaporization takes place when the particles in a liquid gain enough energy to form a gas. • Vaporization that only occurs on the surface is called evaporation • Example: Shrinking puddle

  8. Changes between Liquid & Gas Vaporization takes place when the particles in a liquid gain enough energy to form a gas. • Boiling: from a liquid to a gas below its surface and at the surface • Boiling point: temperature at which a liquid boils

  9. Changes between Liquid & Gas The opposite of vaporization is called condensation. • Condensation occurs when particles in a gas lose thermal energy to form a liquid

  10. Brain Break

  11. Changes between Solid & Gas • Sublimation, particles of a solid that go directly to a gas
