Question

Define surface tension.

Answer 1

the tension of the surface film of a liquid caused by tge attraction of the particles in the surface layer of the bulk of liquid which tends to minimize surface area

Answer 2

Answer:

Surface tension may be defined as force per unit length perpendicular to an imaginary line on the surface of liquid.

lt is generally denoted by the symbol T.

and

$\boxed{\boxed{T = \frac{F}{l}}}$

The unit of surface tension is Newton per metre( N / m).

NOTE::-

Surface tension is a surface phenomenon depends upon nature of liquid, temperature and medium above the surface etc.
