A chemical reaction is endothermic if it absorbs heat from its surroundings. It is exothermic if it gives off heat to its surroundings. In her chemistry class, Lily is given a salt (ammonium nitrate) and a beaker of water at 60 ∘F. She dissolves the salt in the water and sees that the temperature of the solution is now 50 ∘F. Did the temperature of the solution go up or go down? By how many degrees? What kind of reaction has occurred?
