Answer:
Chemically , when Quick lime ( calcium oxide) is added to water (dihydrogen oxide) , the following reaction takes place :-
CaO (s) + H20 (l) →Ca(OH)2 + energy
Here , Slaked lime (calcium hydroxide) is formed with liberation of heat.
Hence , the process is a combination and exothermic reaction.
