Establish the relationship between surface tension and surface Enery.
Answers
Answer:
Surface energy -
Surface energy is the work required to increase unit area in creating new surface at constant temperature, pressure and composition.
Surface tension-
the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
Explanation:
To obtain a expression for surface energy, take a rectangular frame ABCD having a wire PQ which can slide along the sides AB and CD. Dip the frame in soap solution and form a soap film BCQP on the rectangular frame. There will be two free surfaces of film where air and soap are in contact.
If temperature of the film remains constant in this process, this work done is stored in the film as its surface energy
