Why is a water droplet bigger on a less resistant surface, and vice-versa?
I'm wondering why that if you dropped a water droplet on a specially treated surface, the droplet is smaller than a normal water resistant surface?
the specially treated surface interacts with the droplet's surface tension causing it to become reduced and less able to maintain a nice big drop. The special treatment of the surface is said to be a "wetting agent". These wetting agents are used for example in a dishwasher to prevent droplets from forming on glassware as the water dries. Wetting solution is used by contact lens wearers to make the lens get coated with water more easily, quickly and evenly. Photographic film and picture processing uses a wetting agent before drying to eliminate water spots.
