Dissolution overall can be either endothermic or exothermic, depending on whether more energy was used to break the bonds, or more energy was released when new bonds were formed. If more energy is released in making bonds than is used in breaking bonds, the process is exothermic. If more energy is used than is released, the process is endothermic.

Examples include Urea [CO(NH2)2], Potassium Nitrate [KNO3] and Ammonium Nitrate [NH4NO3]. All are commonly found in "Instant cold packs" that become cold when you rupture the inner bag by depressing the pack gently but firmly. When then inner water makes contact with the chemicals listed above inside the outer bag of the pack, the endothermic reaction begins. This is the source of the cold temperature these types of Instant Cold Packs produce.
