  1. Chapter 2ChemistryLesson 2Changes of StateEssential Questions:1.) What happens to particles of a solid as it melts?2.) What happens to particles of a liquid as it vaporizes?3.) What happens to particles of a solid as it sublimes?

  2. Melting- solid to a liquid The particles vibrate fast and break free from their fixed position Particles in a liquid Particles in a solid

  3. Freezing- liquid to a solid The particles move slowly and begin to take a fixed position Particles in a liquid Particles in a solid

  4. Evaporation- liquid to a gas at the surface level Some of the particles on the surface speed up Particles in a liquid Particles in a gas

  5. Boiling- liquid to a gas below and at the surface level Particles below the surface speed up and break the surface Particles in a liquid Particles in a gas

  6. Condensation- gas to a liquid The particles slow down Particles in a gas Particles in a liquid

  7. Sublimation- surface particles of a solid form a gas Surface particles of a solid speed up Particles in a gas Surface particles in a solid
