Cold packs are a common household item that can be used to help lessen pain and muscle spasms as well as swelling and bleeding around the injury. After injuries like ankle sprains, ice packs are often used (Southern California Orthopedic Institute 2014). Dissolving an ionic compound like table salt involves energy, however, some salts consume energy from the surroundings to dissolve in water, thus, leading to excellent endothermic reactions. This concept is applied in the making of cold packs. The cold packs contain a sealed plastic bag containing mixtures of salts that undergo endothermic reactions when dissolved in water. For example, Ammonium Nitrate, and Sodium Acetate. This sealed bag contains salts and is surrounded by a layer of water. When this cold pack is squeezed or popped, the salts come into contact with water and dissolve. The endothermic reactions set in, leading to a significant drop in temperature, thus, making these cold packs extremely effective (Poison Control 2019). Enthalpy is the h
