Question

In a liquid, the energy required to increase the surface of the area by a unit amount is called :a.dipole-dipole force. b.viscosity. c.capillary action. d.surface tension. e.hydrogen bonding

Answer 1

D. Surface tension.

Step-by-step explanation:

Surface tension is defined as the energy required to increase the surface area of a liquid by a unit amount.

The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:

A molecule in a liquid experiences cohesive forces with other molecules in all directions while molecules at the surface of a liquid experiences only net inward cohesive forces.
