The surface tension of water is 72 dyne/cm. In SI unit, it is 0.072 N/m

Given that Surface tension of water = 72 dyne/ cm

We know that,

1 Dyne = 10-5 N and 1 cm = 10-2 m

Therefore, 72 dyne/cm = (72 x 10-5)/10-2 N/m

On simplifying we get

= 72 x 10-3 N/m

= 0.072 N/m

Surface Tension

1. Surface tension is described as a phenomena that happens when the surface of a liquid comes into contact with another phase (it can be a liquid as well). The least amount of surface area is often acquired by liquids. The liquid’s surface behaves like an elastic sheet.
2. Surface tension, which tends to minimise surface area, is the tension of a liquid’s surface film brought on by the attraction of the surface layer’s particles to the liquid’s bulk.
3. The forces of attraction between the particles in the supplied liquid as well as the forces of attraction of the solid, liquid, or gas in contact with it affect surface tension. The effort or energy necessary to remove the surface layer of molecules in a unit area can be conceived of as being roughly equivalent to the energy responsible for the phenomenon of surface tension.

Summary:-

The Surface Tension of water is 72 dyne/cm. Convert it in SI unit

The surface tension of water is 72 dyne/cm. In SI unit, it is 0.072 N/m. Surface tension is the tendency of fluid surfaces to shrink into the minimum surface area possible.
