Energy in the form of heat is exchanged in almost every chemical reaction or change in state. Some reactions require heat to proceed; other reactions release heat as they occur. With the Exploring Energy Changes: Exothermic and Endothermic Reactions—ChemTopic™ Lab Activity, investigate physical and chemical processes and classify them as exothermic or endothermic to get a feel for the amount of heat absorbed or released in physical and chemical reactions.
