Text Solution
Verified by Experts
The correct Answer is:
A
When quick lime reacts with water, a large amount of heat is released along with the formation of calcium hydroxide. Similarly, the process of dissolving an acid or base in water is a highly exothermic reaction. Evaporation of water and sublimation of camphor are endothermic reactions.
