You might think of chemical reactions as occurring exclusively in laboratories, but in reality, they occur in the world around us and in our own bodies every day. . Section 20.1. Objectives ~. Compare and contrast exothermic and endothermic chemical reactions. Analyze the energy diagrams for typical chemical reactions. Illustrate the meaning of entropy and trace its role in various processes. Boiling water. Rusting. Evaporation . Decomposing . Baking. Freezing . Warm Up 8.1: Determine if the following is chemical or physical- . answers. Boiling water-. physical. Rusting. - chemical. Evaporation -. By majd Khalid and Mohammed. The difference. exothermic. Exothermic substances are substances that release energy in the form of heat causing the temperature of the surroundings to increase thus generating a positive change in temperature.
