Exothermic reaction

Explanation:

In an exothermic reaction the products enthalpy is lower than the reactants because in an exothermic reaction the heat is released to the surroundings.

An endothermic reaction occurs the opposite, the products have a higher enthalpy than the reactants, because it absorbs the heat from the surroundings.

Reactions between liquids and between solids, can be either exothermics or endothermics
