Expert Answer
The property of a liquid due to which its free surface at rest behaves like a stretched membrane and tries to acquire a minimum surface area is known as surface tension.
The cause of surface tension is inter-molecular forces.
Surface tension is measured as force per unit length acting on arbitrary line drawn on free surface.
