Answer 1

Endothermic reaction:

• “The reaction in which heat is consumed is called an endothermic reaction.”
• The reaction produces a cooling effect.

The reaction of Ammonium chloride with water:

• When Ammonium chloride is dissolved in water, it undergoes an endothermic reaction.
• Thus, the solution becomes cooler.
• Hence, the change is endothermic.
