Question

ii) What is surface fim
​

Answer 1

Answer:

Surface film tension is the property of a liquid by which it acts as if its surface is a stretched elastic membrane. This tension allows insects to stand on the water’s surface. Surface film tension is caused by the attraction of water molecules to each other; in addition, the surface molecules are attracted to the underlying molecules

Answer 2

Explanation:

surface film is the thin film of liquid near its surface and having thickness equal to the molecular range of attractions for that liquid. the phenomenon of surface tension is associated intimately with this film.
