Consider the following three processes: (1) Melting of ice at room temperature (2) Boiling of water at 101°C (3) Dissolving of NH4NO3 with water in an instant cold pack? Which statement(s) that are true about ALL three of the given processes? (Choose one or more)(A) Endothermic(B) Exothermic(C) Nonspontaneous(D) Spontaneous(E) none of these statements can be used to describe all three processes

Option (A) is the correct answer.

Explanation:

Exothermic reaction is defined as the reaction in which release of heat takes place. Whereas endothermic reaction is defined as the reaction in which heat is absorbed by the reactant molecules.

Thus, we can conclude that for the given statements its is true that ALL three of the given processes are endothermic.
