1) Contrast the concepts of temperature and heat flow in macroscopic and microscopic terms. Understand that heat is a form of energy and temperature is a measure of average kinetic energy of a molecule.
2) Draw and interpret heating and cooling curves and phase diagrams. Analyze the energy changes involved in calorimetry by using the law of conservation of energy quantitatively (use of q = mcΔT) and qualitatively.
3) Distinguish between endothermic and exothermic reactions by constructing potential energy diagrams and explain the differences between the two using chemical terms (e.g., activation energy). Recognize when energy is absorbed or given off depending on the bonds formed and bonds broken.
4) Analyze energy changes to explain and defend the law of conservation of energy.
