Key Words...
Chemical/Physical Change
  • What is a physical property?
  • What is a physical change?
  • What is a chemical property?
  • What is a chemical change?
  • The difference between a physical and chemical change


States of Matter
  • The four states of matter…solid, liquid, gas, and plasma




Phase Change
  • Temperature does not change during a phase change
  • Freezing is changing from a liquid to a solid
  • Melting is changing from a solid to a liquid
  • Boiling is changing from a liquid to a gas
  • Condensing is changing from a gas to liquid
  • Sublimation is changing from a solid to a gas



Kinetic Molecular Theory



Using the Gas Laws (Boyle's and Charles)

Video Examples of Boyle's and Charles Law Problems!


Mixtures/Compounds


  • Elements are atoms of the same type
  • Compounds are made of two or more elements (Click Here for Video!)
  • Heterogeneous mixture is a mixture that different materials can be distinguished easily (Click Here for Video!) (Click Here for Video!)
  • Homogenous mixtures are two or more substances that are evenly blended throughout
  • A suspension is a heterogeneous mixture that the particles are allowed to settle
  • Diffusion is the spreading out of particles from high concentration to low concentration

  • Solute is the substance that you dissolve
  • Solvent is the substance that you are dissolving in
  • Concentration is amount of solute/amount of solvent
