Vedclass · Answer

(B) Surface tension is a property of liquids arising from the intermolecular forces of attraction. Specifically,it is caused by cohesive forces,which are the attractive forces between molecules of the same substance. At the surface of a liquid,molecules experience a net inward pull because there are no liquid molecules above them to balance the cohesive forces from the molecules below and to the sides. This inward pull results in the surface acting like a stretched elastic membrane,a phenomenon known as surface tension. Therefore,the correct option is $B$.
