Homework Answers
Answer:
Surface tension is the Intermolecular force that means liquid caused by a attraction between the molecules which tends to minimise the surface area.
As a result of this the drops of water tends to assume a spherical shape.
The water molecules are having the H-bonds between them. During the different concentrations of the solute the attraction between the molecules may increase or decrease. This influences the surface tension.
