In a typical cold pack (used for sports injuries), a salt such as ammonium nitrate is kept in a separate pouch from a bag of water. When the pouch is punctured, the salt readily dissolves in the water, and the pack becomes noticeably cooler to the touch (temperature decreases from room temp to about 5 oC). Based around le Charlier principle conclude the signs for ΔHº, ΔSº, and ΔGº for the solvation of ammonium nitrate in water.
