  1. According to Boyle's Law, what kind of relationship does pressure and volume have?
    indirect
  2. According to Charle's Law, what kind of relationship does temperature and volume have?
    • - Higher temperature, greater volume
    • -lower temperature, smaller volume
    • direct
  3. Changes between liquid and gas
    • - vaporization
    • - evaporation
    • - boiling
    • - condensation
  4. Changes between solid and gas
    - sublimation
  5. Changes between solid and liquid
    • - melting - ex. water
    • - freezing - ex. ice
  6. Explain Charles Law
    Charles found that when the temperature of a gas is increased at constant pressure, it's volume increases. When temperature of a gas is decreased at constant pressure, it's volume decreases.
  7. Explain Boyle's Law
    Boyle found that when a pressure of a gas at constant temperature is increased the volume of the gas decreases when pressure is decreased, volume increases - ex. opposite/indirect
  8. What are 2 types of solids
    • - crystaline - ex. diamond, salt,
    • - amorphous - ex. butter
  9. What are 3 factors that are important in working with the gas
    • - volume
    • - pressure
    • - temperature
  10. What are the 2 properties of liquid
    • - viscosity
    • - service tension
    • - ex. high viscosity, thick liquid
    • - ex. low viscosity, thin/watery liquid
  11. What happens to pressure when temperature is increased?
    When temperature of a gas at constant volume is increased, the pressure of the gas increases.
