In SI unit the surface tension of water is 0.072 N/m
.

Explanation:

Dyne and Newton, both are units of force. While Dyne is specified in C-G-S(Centimeter – Gram – Second) unit system, Newton is specified in modern SI unit system.

We know that 1 Newton = dyne.

Surface tension of water - 72 dyne/cm.

1 dyne/cm = 0.001 N/m

72 dyne/cm = 0.072 N/m

Capillarity or Capillary action or capillary motion or wicking is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity.

Some applications of capillarity are:

a. Towels soak water on account of capillarity.

b. Oil rises in the long narrow spaces between the threads of the wick as they act as a capillary.
