Surface tension

Vedclass · Answer

(A) Surface tension is the property of a liquid surface that allows it to resist an external force,due to the cohesive nature of its molecules. Water has a high surface tension because of the strong hydrogen bonding between its molecules. This property creates a 'skin' on the surface of the water,which supports small organisms like planktons,allowing them to move or float on the surface without sinking.
