In a liquid,the energy required to increase the surface of the area by a unit amount is called
A) viscosity.
B) surface tension.
C) dipole-dipole force.
D) hydrogen bonding.
E) capillary action.

Question

Quizplus · Accepted Answer

The energy required to increase the surface area of a liquid is called surface tension. This is the result of the molecules at the surface of the liquid being pulled towards their neighbors and creating a strong cohesive force. Viscosity refers to a liquid's resistance to flow, dipole-dipole force and hydrogen bonding describe the intermolecular interactions within a liquid, and capillary action refers to the ability of a liquid to flow against gravity in narrow spaces.
