Answer is: hot pack.
This is exothermic reaction (energy or heat is released), because reactants have higher energy than products of reaction. Hot pack is mixture of water and salt (usually magnesium sulfate or calcium chloride). When salt dissolves in water, more energy is released than taken in, so process is exothermic.
