Definitions from the WebEndothermic EnergyEndothermic energy refers to a type of energy that is absorbed from the surroundings to initiate or sustain a chemical reaction or a physical change. It is commonly associated with processes that require heat input to occur. Senses and UsagesSense 1: ChemistryIn chemistry, endothermic energy refers to the energy absorbed during a chemical reaction, causing the reaction to be accompanied by a decrease in temperature. This energy is required to break the existing bonds in reactant molecules and form new bonds in the resulting products. Example: The decomposition of ammonium nitrate is an endothermic reaction, as it absorbs heat energy from the surroundings, causing a noticeable decrease in temperature. Sense 2: PhysicsIn physics, endothermic energy is linked to physical changes that require energy absorption, resulting in a drop in temperature. These changes can include phase transitions or the conversion of solid to gas (sublimation). Example: The process of dry ice (solid carbon dioxide) sublimating directly into a gas is an example of an endothermic physical change.
