Question

The ratio of surface energy of the surface area is

Answer 1

surface tension

CONCEPT:

Surface tension: Surface tension is a measure of the cohesive forces between liquid molecules present at the ssurface

Molecules at the surface of a liquid are partly exposed to the surrounding. The molecules at the liquid-air interface experience fewer interactions and have more energy to escape to the surrounding.

Therefore, energy is required to bring molecules from the bulk of the liquid to the surface. The stronger the intermolecular interaction, the greater is the energy required to increase the surface area of a liquid.

This energy is called surface energy and is related to surface tension as:

Surface tension = Surface Energy/ Area

Answer 2

Concept:

The cohesive forces between liquid molecules present at the surface are measured by surface tension.

Molecules on a liquid's surface are partially exposed to the environment. At the liquid-air interface, molecules have fewer interactions and more energy to escape into the environment.

As a result, energy is necessary to transport molecules from the liquid's bulk to the surface. The more powerful the intermolecular contact, the more energy is required to raise a liquid's surface area.

Find:

The ratio of surface energy with respect to the surface area.

Solution:

$Surface \quad tension = \frac{Surface \quad energy}{Area of the surface}$
