D) Archimedes' principle.
E) viscosity.

Question

Quizplus · Accepted Answer

The reason for the spherical shape of a dew drop is surface tension. This is the force that exists on the surface of a liquid because of the imbalance in intermolecular forces at the surface. The forces attract the liquid molecules towards each other, which minimizes the surface area of the liquid. Consequently, when a dew drop forms on a surface due to condensation, the force of surface tension pulls the liquid into a shape with minimal surface area, which is a sphere.
