A drop of water placed on a smooth, dry surface will form a dome-shaped droplet instead of flowing outward in different directions. Which of these best explains this observation?

The bonds between hydrogen and oxygen atoms are very strong.

The electrons in the atoms attract the electrons in the other atoms.

Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Water molecules near the surface produce more buoyant force than water molecules within the liquid.

i really need help I think its a or d

Search for "cohesion". It is the attraction between same molecules. The molecules at the surface has less molecules that it can attract because it is surrounded by less.

I think its d

am I correct ?

anonymous · Answer

C.   The water molecules attract each other more strongly than they are attracted to the surface, thus they do not wet it effectively.
