Learning objectives At the end of this lecture, you will be able to: 1) Explain how the structure of water affects its chemical properties, including density, surface tension, specific heat, and heat of vaporization. 2) Be able to compare potential energy with kinetic energy and give examples of each. 3) Define ‘free energy’ and relate the gain or loss of free energy to reactions in biological systems. 4) When presented with ! G values for biological reactions, be able to state whether the reaction is exergonic or endergonic / spontaneous or nonspontaneous.

Vocabulary: These are the terms required to understand water and energy: – hydrogen bond (Fig 2.12, pg 22) – hydrophilic/hydrophobic (Fig 2.13, pg 22) – 1 st Law of thermodynamics (Fig 2.18, pg 29) – kinetic energy (Fig 2.18, p27) – potential energy (Fig 2.18, p27) – entropy and 2 nd Law of thermodynamics (pg29) ! G (Gibbs free energy change) (pg30) – exergonic vs. endergonic (pg30) – spontaneous / nonspontaneous (pg29) – free radical (Fig 2.23, pg32)
