Question

define surface tension state its unit​

Answer 1

Explanation:

Thus, the units of surface tension are dynes per centimetre or Newton per metre i.e. Nm-1 in the S.I. system. As a result of inward pull on the molecules at the surface, the surface of the liquid tends to the smallest possible area for a given volume of the liquid. This gives the lowest energy state of the liquid.

Answer 2

Answer:

The cohesive force between liquid molecules are responsible for the phenomenon known as surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface. SI unit is newton per meter.
