  • 2. 
    As gas pressure increases, solubility ___________.
  • 3. 
    As solids' pressure increases, solubility ___________.
  • 4. 
    A polar molecule (like water) is more likely to dissolve in a ___________ solution.
  • 5. 
    A non-polar molecule (like oil or hexide) is more likely to dissolve in a ___________ solution.
  • 6. 
    When dissolving a compound such as sugar (glucose), the partially positive ends of the water molecule will attach to the __________ ends of the sugar molecule (C6H12O6), and vice versa.
  • 7. 
    Solubility describes the amount of ___________ that will dissolve in a given amount of solvent at a given temperature.
  • 8. 
    What is one way that dissolved oxygen does NOT get into water? (Hint: Think of the formulas for photosynthesis/respiration)
    • A. 

      Aeration

    • B. 

      The surface (atmosphere)

    • C. 

      Cellular respiration

    • D. 

      Photosynthesis

  • 9. 
    What is a way that dissolved oxygen can NOT affect aquatic life (aerobic and anaerobic)?
    • A. 

      DO levels that decrease will kill fish because they have less O2 to respire with.

    • B. 

      Decreased DO levels will cause a bacteria increase which can potentially be harmful.

    • C. 

      Increased bacteria numbers from decreased DO levels can take all of the O2 from aerobic aquatic life.

    • D. 

      Dissolved oxygen is essential for water; therefore, it will have no effect on aquatic life.
