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?
a. The bonds between hydrogen and oxygen atoms are very strong.
b. The electrons in the atoms attract the electrons in the other atoms.
c. The molecules at the surface strongly cohere to the other molecules on the surface with them.
d. Water molecules near the surface produce more buoyant force than water molecules within the liquid.
