PPT-Exothermic or endothermic?

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. Processes & Reactions. Exothermic. Endothermic. Process. Heat. exiting a substance. Ex: water freezing. Physical change. Heat entering a substance. Ex: water evaporating. Physical. change. Reaction.
