____ is the merging of small droplets into large droplets.

Explanation:
Coalescence is the merging of small droplets into larger droplets. When droplets collide, the thin film between them can rupture, allowing the droplets to fuse into a bigger drop. This reduces the total surface area and is a key way emulsions become unstable over time. By contrast, creaming is caused by density differences driving droplets to rise or settle without any fusion; flocculation is droplets sticking together into loose clusters while staying as separate droplets; and breaking refers to mechanical disruption that breaks droplets apart rather than fusing them.
