What is surface tension?

Surface Tension
Surface tension is a property of liquids caused by the attraction of the molecules at the surface of the liquid. This attraction creates an invisible film on the surface of the liquid that affects how the liquid behaves. This tension is strong enough to support objects that rest on the surface of the liquid

surface tension
Surface tension is the property of a liquid that causes it to behave as if it had an elastic skin on its surface. This property is due to cohesive forces between the molecules of the liquid.
Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.
Adhesion is the attractive force between different molecules, which causes them to stick to each other.

Did you know?
Surface tension can be used to transport objects on the surface of a liquid, such as water, without the object sinking. Surface tension can cause water to form droplets, which is why raindrops are round. Surface tension is what makes a paper clip float on top of the water.
