Question:
Evaporation of water is
Evaporation of water is
Show Hint
Endothermic reactions absorb heat, while exothermic reactions release heat.
Updated On: May 5, 2025
- An exothermic reaction
- A process during which neither heat is released nor heat is absorbed
- A process of chemical reaction
- An endothermic reaction
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Evaporation of water is an endothermic process because it requires the absorption of heat from the surroundings to overcome the intermolecular forces in the liquid phase.
