Evaporating water endothermic or exothermic

WebThe phenomenon of evaporation is an endothermic process. It’s an endothermic process because the system needs the energy to break bonds, and this way, the liquid changes into a gaseous state. “Endo” meaning within, and “therm” meaning heat. The boiling point is the temperature at which a liquid converts into a gas. WebIf ΔH is positive, the process absorbs heat from the surroundings and is said to be endothermic. If Δ H is negative, the process releases heat to the surroundings and is …
