## What is the formula for calculating surface tension?

Surface tension is defined as, The ratio of the surface force F to the length L along which the force acts. Mathematically, surface tension can be expressed as follows: T=F/L.

### What is difference between viscosity and surface tension?

The viscosity of a fluid is a measure of how sticky the fluid is, on the other hand, Surface tension is the elastic property of a fluid which makes it acquire the least surface area possible.

What is surface tension and its SI unit?

The force per unit length perpendicular to a line drawn in the surface of the liquid is the surface tension. Its SI unit is newtons per metre, and its CGS unit is dynes per centimetre. The dimensions are MT−2.

Is surface tension dependent on viscosity?

Surface tension is influenced by the cohesive forces of the molecules and viscosity is related to the shear stress in the solution.

## Is viscosity directly proportional to surface tension?

Well, Surface tension is the property of a liquid’s surface which is caused by unbalanced forces on surface molecules that pull toward the main (underneath) part of the liquid. And, so the general notion is that there is no absolute correlation between viscosity and surface tension.

### What happens to surface tension when viscosity increases?

As the temperature increases, viscosity decreases. Surface tension decreases with an increase in temperature.

How does viscosity affect surface tension?

Both viscosity and surface tension are affected by changes in temperature. As the temperature rises, liquids lose viscosity and decrease their surface tension — essentially, becoming more “runny” than they would be at cooler temps.

What is the difference between viscosity and surface tension?

Viscosity is the measure of how resistant to flow a liquid is, while surface tension is defined as how resistant the surface of a liquid is to penetration. Both viscosity and surface tension are affected by changes in temperature.

## What chemicals reduce surface tension?

Surfactant is a chemical substance which is used to lower the surface tension in a liquid. It is also known as surface active agent, when dissolved in water, can remove the dirt from the surfaces. Surfactants also work as wetting agents and foamers.

### What are the properties of surface tension?

Surface tension is a property of a liquid surface that causes it to act like a stretched elastic membrane. Its strength depends on the forces of attraction among the particles of the liquid itself and with the particles of the gas, solid or liquid with which it comes in contact.

What is the formula for calculating surface tension? Surface tension is defined as, The ratio of the surface force F to the length L along which the force acts. Mathematically, surface tension can be expressed as follows: T=F/L. What is difference between viscosity and surface tension? The viscosity of a fluid is a measure of…
