Question

H2O(I)+40.7 KJ > H2O(g)endothermic or exothermic

Answer 1

ANSWER

Endothermic reaction

EXPLANATION

Given that;

$\text{ H}_2O_{(l)}\text{ + 40.7KJ }\rightarrow\text{ H}_2O_{(g)}$

In the reaction above, there is a transition from liquid water to steam. This phase change is called boiling.

During the process, heat is absorbed from the surroundings.

Therefore, the reaction is an endothermic reaction.
