GEO307 Chapters 5-6 I. Water Molecule (H 2 O) a. Covalent bonds – pair of shared electrons b. Polar molecule – slight asymmetry in charges c. Hydrogen bonds – weak attraction based on charge asymmetry a. b. Temperature = average kinetic energy c. Heat – measure of TOTAL amount of kinetic energy III. Changes of state (ice, water, water vapor) a. Chemical properties (# of bonds) require extra energy to break b. Latent heat of fusion – solid to liquid (or vice versa), 80 calories c. Latent heat of vaporization – liquid to gas (or vice versa), 540 calories d. Heat required to break hydrogen bonds e. IV. Heat capacity – quantity of heat required to produce a unit change in temperature (hydrogen bonds give water high heat capacity) a. Cohesion – attraction with its electric charges b. Surface tension – measure of how difficult it is to stretch or penetrate surface
