Why does waterproof raincoat not wet in rain?
In the case of a raincoat, the cohesive force in water molecules is obviously far larger than the adhesive force, therefore water does not attach to the raincoat surface. The angle of contact between the water and material of the raincoat is obtuse. So the rainy water does not wet the raincoat.
