AP Biology Chapter 3 Assignment
After reading this chapter and attending lecture, you should be able to:
1. Describe how water contributes to the fitness of the environment to support life.
2. Describe the structure and geometry of a water molecule, and explain what properties
emerge as a result of this structure.
3. Explain the relationship between the polar nature of water and its ability to form
hydrogen bonds.
4. Distinguish between heat and temperature.
5. Explain how water's high specific heat, high heat of vaporization and expansion upon
freezing affect both aquatic and terrestrial ecosystems.
6. Explain how the polarity of the water molecule makes it a versatile solvent.
7. Define molarity and list some advantages of measuring substances in moles.
Define the following terms:
cohesion
dissociation
solute
kilocalorie
hydrophilic
pH scale
molecular weight
evaporative cooling
solution
temperature
surface tension
