Surface tension is the force that opposes the adhesion of a liquid layer to a solid surface. The force is due to surface tension forces between molecules of the liquid and the molecules of the solid. Surface tension is a result of the cohesive forces between molecules of a liquid and holds them together.
Surface Tension Definition
Surface tension is a property of liquids and a surface tension force is the force that liquid molecules exert on each other to minimize surface area. Surface tension is a measure of the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid.
If a liquid has a low surface tension, its molecules will Spread out and the liquid will be less cohesive, which will lead to a decrease in surface tension force. The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules is surface tension. A surface tension force is the force that liquid molecules exert on each other to minimize surface area.
Formula of Surface Tension

Here,
x = Surface Tension
F = Force
L = Length
Surface tension is a force that holds liquids and gases together. It’s the reason water droplets stay in a drop on a windowpane and why air bubbles form inside juice containers.
When two objects are brought close to each other, surface tension pulls them apart. This phenomenon is used all the time – for example, when you wet your hand and then sprinkle water across the kitchen floor.
Unit of Surface Tension
The unit of surface tension is the dyne/cm2, which is equivalent to a pennyweight per cubic meter.
Example of Surface Tension
Surface tension is a force that keeps water droplets together and prevents them from spreading out. It’s responsible for things like rainbows, oil slicks, and bubbles.
One example of surface tension in action is when you wet a cloth and it takes a while for the water to drip off – this is due to surface tension. Surface tension can also be used in science – it’s what allows scientists to study liquids under high pressure.
Conclusion
Surface tension is the tension that exists between the surface of a liquid and the molecules of the liquid. This tension is responsible for a variety of phenomena, such as capillary action and surface tension forces.
