The conclusion of the student would be that the dissolution of ammonium nitrate is endothermic.
<h3>What are endothermic reactions?</h3>
They are reactions in which heat is absorbed from the surrounding. The consequence is that the reaction mixture's temperature is always lower.
Thus, the energy of the products is always higher than the energy of the reactants in endothermic reactions.
For endothermic reactions, the enthalpy change is always positive.
