Did you know?
WebApr 12, 2024 · Exothermic phase transitions release heat (thermal energy) into the environment. Examples of endothermic transitions are the boiling of water and the melting of ice, which take heat from the environment. Exothermic transitions are the condensation of water vapor and the freezing of liquid water, that gives heat to the environment. WebExothermic and endothermic reactions When a chemical reaction occurs, energy is transferred to or from the surroundings. There is usually a temperature change. For …
WebApr 11, 2024 · Endothermic and exothermic processes refer to the absorption or release of energy (usually in the form of heat) during chemical reactions and physical transformations. Endothermic process: 1. ... Freezing of water: When water changes from liquid to solid state, the lost energy is released as heat. c. Respiration: The process of breaking down ...
