- energy is absorbed
- energy is liberated
- energy is neither liberated nor absorbed
- process is independent of energy
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Surface Area Analysis
When small droplets coalesce into a single large drop, the total surface area decreases.
Step 2: Energy Relation
Surface energy is proportional to surface area ($E = S \times A$).
Step 3: Conclusion
Since the surface area decreases, surface energy is released (liberated).
Final Answer: (B)
