What is the term for forming larger droplets from smaller droplets?

• A. Condensation
• B. Agglomeration
• C. Emulsification
• D. Atomization

Answer: (B)

This concept focuses on how droplets interact to change size by sticking together. When small droplets collide and adhere to one another, they form bigger assemblies of droplets. That process is called agglomeration. It describes droplets clumping into larger droplets through physical contact and adhesion, without a chemical reaction. This differs from condensation, where vapor turns into liquid droplets rather than existing droplets merging. It also differs from emulsification, which is about dispersing one liquid into another immiscible liquid to form a mixture, not about droplets growing by merging. Atomization, on the other hand, is the breaking apart of a liquid into many smaller droplets, the opposite of forming larger ones. So, the term that best fits forming larger droplets from smaller droplets is agglomeration.
