Explanation:

Surface tension is the phenomenon that occurs at the interface of two immiscible liquids or a liquid and a solid surface. It refers to the cohesive forces that exist between the molecules of a liquid at the surface, which leads to the formation of a thin layer or film. Surface tension is measured by the amount of energy required to increase the surface area of the liquid.

Cohesion:

Cohesion refers to the tendency of molecules of the same substance to stick together. In the case of a liquid, it is the force between the molecules that causes them to stick together and form a bulk fluid. Cohesion is responsible for the surface of a liquid to behave like a stretched membrane, which resists any external force that tries to break it. Cohesion is the force that creates the surface tension in a liquid.

Adhesion:

Adhesion refers to the tendency of molecules of different substances to stick together. When a liquid comes in contact with a solid surface, the molecules of the liquid are attracted to the molecules of the solid surface. This attraction leads to the formation of a thin layer of the liquid on the surface of the solid, which is called the meniscus. Adhesion is responsible for the capillary action, which is the ability of a liquid to flow in narrow tubes or between two closely spaced surfaces.

Surface tension:

Surface tension is due to the cohesive forces between the molecules of a liquid at the surface. The cohesive forces between the molecules at the surface are stronger than the forces between the molecules in the bulk of the liquid. This creates a stretched membrane-like surface, which resists external forces. Surface tension is responsible for phenomena like the formation of drops, which are spherical due to the minimization of the surface area, and the buoyancy of small objects on the surface of a liquid.

Conclusion:

In conclusion, surface tension is due to the cohesive forces between the molecules of a liquid at the surface, which is a result of the phenomenon of cohesion. Adhesion also plays a role in the formation of surface tension when a liquid comes in contact with a solid surface. Surface tension is an important phenomenon that has many practical applications, including in the formation of bubbles, the functioning of biological membranes, and the design of microfluidic devices.
