    Answer:

    H₂0_{(s)}  +  heat  →  H₂O(l)  

    Explanation:

    An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.

    On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.
