Which of the following is NOT a key property of surface tension?

Surface tension is a physical property of liquids that arises from the cohesive forces between liquid molecules, particularly evident in water. This property is characterized by various phenomena, such as the ability of small objects to float on the surface of the water without sinking.

The evidence of surface tension is seen in its ability to support small weights on the water surface, which is a direct result of the molecules at the surface pulling together more tightly than those in the bulk of the liquid. This creates a "skin" effect, allowing certain objects less dense than water, like a paperclip, to rest atop the surface without breaking through.

Another key aspect of surface tension, driven by cohesive forces among water molecules, is the formation of this "skin" effect, which allows insects like water striders to walk on water.

However, the capacity to allow fast-moving currents does not describe a property of surface tension itself. While surface tension can influence the behavior of water surfaces, such as preventing small objects from sinking, it does not inherently contribute to the movement or speed of currents within the water body. Currents are primarily governed by factors like gravity, wind, and the topology of the water body, rather than surface tension. Thus, identifying the capacity to allow fast-moving
