Dissolution of quicklime in water
Solidification of water
Rusting and respiration
All of the above

Answer 1

Explanation:

When water reacts with quick lime, calcium hydroxide is formed along with release of heat. Thus, it is an exothermic reaction. The process of diluting a concentrated acid is a highly exothermic process. Evaporation of water and sublimation of camphor are examples of endothermic reactions.

Here (i) Reaction of water with quicklime and (ii) Dilution of an acid are the exothermic reaction.
