Vedclass · Answer

(A) molecule at the surface of a liquid experiences an unbalanced cohesive force directed into the bulk of the liquid. This is because the number of molecules in the liquid phase below the surface is much greater than the number of molecules in the vapor phase above the surface. Consequently,the net force on a surface molecule is directed downward,perpendicular to the surface,pulling it into the liquid.

In what direction does the force act on a molecule at the surface of a liquid? Explain.
