  1. Matter
    Anything that has mass and occupies space
  2. Pure Substance
    • Matter that contains only one kind of particle
    • i.e.- Helium and Water
  3. Mixture
    • Matter that contains more than one kind of particle
    • i.e.- Salt water, Air
  4. Element
    • A pure substance that cannot be broken down into ssimpler parts by chemical methods
    • i.e.- Heluim
  5. Compound
    • A pure substance made up of two or more different elements that are chemically combined
    • i.e.- Water
  6. Physical Property
    • A characteristic of a substance that can be observed and measured without changing the identity of the substance
    • Can be either quantitative or qualitative
    • i.e.- Hardness, Viscosity, Colour, State
  7. Viscosity
    • The measure of a substance's resistance to flow
    • The more viscous a fluid is, the slower it flows
    • Water and molasses¬†are two fluids with very different viscosities
  8. Melting Point
    • The temperature at which a solid turns into a liquid
    • i.e.- Waters melting point is 0 degrees celcius
  9. Boiling Point
    • The temperature at which a liquid turns into a gas
    • i.e.- Waters boiling point is 100 degrees celcius, yet heliums boiling point is -269 degrees celcius
  10. Solubility
    • A measure of the ability of a substance to dissolve in another substance
    • i.e.- Salt is a solute that easily dissolves in water to produce a saltwater solution
  11. Density
    • The ration of the mass of a substance to the volume it occupies
    • i.e.- A substance has a mass of 5.04 g and a volume of 0.48 cm3, what is the density?
    • ¬†
  12. Chemical Property
    The ability of a substance to change or react, and to form new substances
  13. Combustibility
    The ability of a substance to burn in air
  14. Stability
    The ability of a substance to remain unchanged
  15. Toxicity
    The ability of a substance to cause harmful effects in plants and animals
