"Most scientists define wetness as a liquid's ability to maintain contact with a solid surface, meaning that water itself is not wet, but can make other sensation. But if you define wet as 'made of liquid or moisture', as some do, then water and all other liquids can be considered wet."
Basically Emergence dictates that a group of things (like H2O molecules) can form something greater than the sum of itself (wetness). In the molecules wetness is not a thing, but the interaction of water with something else creates wetness. This concept cannot reasonably be boiled down to the molecular level, it only exists on this plane of existence.
