Answer 2

Answer:

Option d) Creaming is the correct option. It is a reversible emulsion phenomenon.

Explanation:

• Creaming is the rise of dispersed particles towards the surface of an emulsion or an upward movement. This occurs because of the difference in the densities of dispersed particles & serum phase. The two layers are visible and show the optical differences because of different densities.

• Coalescent- It is an irreversible process because the destruction of the film that surrounds the individual globules is involved. The size of the dispersed-phase increases gradually in coalescent which breaks the emulsion.
• Breaking- It refers to the complete separation of the 2 liquid phases in the emulsion. It is also an irreversible process. It is also called cracking.
