The unit of surface tension is?

Answer 1

Surface tension is basically a force acting on the surface of a fluid.

so the units will be newtons(N) and dimensions are MLT-2

But generally we talk in terms of surface tension coefficients which is surface tension per unit length.

Vishesh Madan

Surface tension is perpendicular force acting per uint length of an imaginary line stretched on the surface of a liquid. Therefore, SI units will be N/m, since the value of surface tension for all liquids is very low therefore it is commonly mentioned as mN/m. Dimensions formula for surface tension will be MT-2.In another case Surface tension is also measured as work done to streach a unit surface area of a film, in that case units will be J/m2.K Singh

Answer 2

The Elasticlike force existing on the surface of the body ,esp. a liquid tending to minimize the area of the surface,caused by asymatries in the intermolecular forces between surface molecules.Thanks for reading its true from a science book.

Answer 3

The unit of tension is the same as the unit of force - in the metric system this is the newton (N).

=====

To Tenderwire, who supplied the above answer: No. Tension is a stress (as is compression), which is measured in pascals (N/m2).

Answer 4

The si unit for tension is N/m(newton per meter)

Answer 5

N/m

Answer 6

dynes/cm

Answer 7

Ml°t-2
