Explanation:
When water is added to quick lime, slaked lime is formed and the reaction is highly exothermic which results in the liberation of a lot of heat due to which water starts to boil even when it is not provided with external heat.
The equation to represent the reaction is as follow
CaO(s) + H20(l) ——— > Ca(OH)2(s) + Heat
Quick lime slaked lime
