Is liquid to gas endothermic or exothermic? Is dissolving of a solid in water a chemical or physical change? Is liquid to solid endothermic or exothermic? Which change of state involves a release of energy? Boiling, condensation, melting, or sublimation? What happens to...
Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Ex : C(g)+O(2)(g) to CO(2)+HeatEnergy Reactions that absorb energy or require energy in order to proceed are called endothermic reactions.
