Solution

The setting of cement is an example of an exothermic reaction.
Exothermic reaction is the reaction in which heat is evolved.
The process of hardening of cement is termed as the setting of cement.
Cement on mixing with water forms paste and then the reaction starts between them.
A smooth paste is produced and the paste can be distributed.
The process of changing fluid state to solid-state that is hardening of cement is termed the setting of cement.
During the setting of cement heat is liberated as water reacts with cement so it is an exothermic process.
