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 too strong.
B. The electrons in the atom attract the electrons in other atoms.
C. Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid
D. Water molecules near the surface produce more buoyant force than water molecules within the liquid.

Respuesta :

your answer is C Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Answer:

The correct answer is option C which is, "Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid".

Explanation:

  • In some conditions, a water droplet remains in the droplet form on the dry surface rather than spreading on the whole surface. It covers only remains on the mall part of the surface and making a dome shape.
  • It is due to the fact that the hydrogen bond between the water molecules is much strong than the attraction between the water molecules and surface.
  • Hence the option C is correct.
