Is a cold pack endothermic or exothermic?
The amount of heat released or absorbed by the packs depends on the water and salt concentration. This type of hot pack typically includes a metal disc that provides a site for crystallization when pressed down. What exactly are you trying to do? If you want to keep something cold, water has a high latent heat of fusion and is therefore very effective. A hot pack is formed when an exothermic reaction occurs while the salt and water mixture and heat energy are released as this process increases the temperature of the contents in the package.
Commercial instant cold packs typically use either ammonium nitrate or urea as a salt component; hot packs often use magnesium sulfate or calcium chloride.
