The answer is: hot pack.This is the reaction exothermic (energy or heat is released), because the reactants have greater energy than the products of the reaction. Hot pack is a mixture of water and salt (typically magnesium sulfate or calcium chloride). When the salt dissolves in the water, the more energy is released in fact, so that the process is exothermic.
