Question:
Creaming in emulsion is best described as
Creaming in emulsion is best described as
Show Hint
Creaming = Reversible (Shakable); Cracking = Irreversible (Broken).
Updated On: May 15, 2026
- Irreversible coalescence of droplets
- Reversible phase separation due to density of globules
- Formation of multiple emulsion
- Chemical degradation of emulsifier
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Emulsions are thermodynamically unstable systems that can undergo various forms of physical instability.
Step 2: Meaning
Creaming is the upward or downward movement of dispersed droplets relative to the continuous phase.
Step 3: Analysis
Creaming occurs due to density differences between the two phases (governed by Stokes' Law). Unlike cracking (coalescence), creaming is reversible upon gentle shaking.
Step 4: Conclusion
It is a reversible process where the globules concentrate at the top or bottom. Final Answer: (B)
