Study Guide Questions
- Explain the relationship between the kinetic energy of molecules or atoms in a system, and temperature.
- Explain what it means when someone says, “Water is a polar molecule.” (Bet you hear that all the time!)
- What are hydrogen bonds?
- Why is it difficult to heat up (or cool down) water?
- Why is water such a good solvent? Are there any substances water cannot dissolve? Why or why not?
- What is surface tension? Give some biological examples of why surface tension in water is important.
- What is a surfactant?
- Be able to clearly relate pH and hydrogen ion concentration.
- What exactly does a pH of 4 mean?
- What impact does changing pH have on proteins?
- What are buffers? What do they do? Why are they important?
