Unformatted text preview: Kinetics and Thermodynamics The Flow of energy heat and work Part I. Energy Transformations A. Temperature 1. A measure of the average kinetic energy of the particles in a sample of matter B. Heat (or Heat Energy) 1. The sum total of the kinetic energies of the particles in a sample of matter a. Heat flows spontaneously from matter at higher temperature to matter at lower temperature Part II. Exothermic and Endothermic processes A. Exothermic processes 1. Heat is written on the product of the reaction: 2. the system gives up heat as the surroundings heat up B. Endothermic processes 1. Heat is written on the reactant side of the reaction 2. The system gains heat as the surroundings cool Part III. Units for Measuring Heat Flow A. Joules 1. Heat is usually measured in joules, J a. Heat cannot be measured directly, but is measured by temperature changes when heat is transferred...
