Applied Physics I: Chapter 2: Properties of Matter - Viscosity and Surface Tension

Surface Tension

Definition, Formula

Surface tension is defined as the force per unit length acting along the surface of a liquid.

SURFACE TENSION


Surface tension is a fundamental property of liquids that plays an important role in various natural and industrial processes. It can be observed in everyday life, such as from formation of water droplets, insects walking on water etc.

 

Definition

Surface tension (σ) is defined as the force per unit length acting along the surface of a liquid. It is measured in units of force per unit length (N/m).

The formula to calculate surface tension is

 σ = F / L

Where,

• σ is the surface tension,

• F is the force acting along the surface, and

• L is the length over which the force acts.
