Surface tension is the property of a liquid that causes its surface to act like a thin, elastic membrane. It is caused by the cohesive forces between the molecules of the liquid, which pull the molecules at the surface inward, creating a tension that resists external forces. This tension allows certain insects, such as water striders, to walk on water and causes liquids to form droplets or beads on a surface rather than spreading out.

Surface tension is the force that causes the surface of a liquid to behave like a stretched elastic sheet. It is caused by the cohesive forces between the molecules of the liquid.
- Cohesive forces are the forces that attract molecules of the same substance to each other.
- Surface molecules of a liquid are attracted to the molecules below them and to the molecules on either side of them. However, they are not attracted to the molecules above them because there is nothing above them. This results in a net upward force on the surface molecules.
- The net upward force on the surface molecules causes them to pull together, creating a surface tension.
Surface tension is responsible for a number of phenomena, including:
- The formation of bubbles and drops: The surface tension of a liquid causes it to form bubbles and drops that are spherical in shape. This is because the sphere has the smallest surface area for a given volume, which minimizes the surface tension.
- The rise of liquids in capillaries: The surface tension of a liquid causes it to rise in a capillary tube. This is because the cohesive forces between the liquid molecules are stronger than the adhesive forces between the liquid molecules and the capillary walls.
- The formation of waves: The surface tension of a liquid causes it to form waves. This is because the surface tension resists the deformation of the liquid.
Surface tension is an important property of liquids that affects a wide range of phenomena. It is responsible for the formation of bubbles, drops, and waves, and it also affects the rise of liquids in capillaries.
