Question

Describe the method of finding surface tension of water using capillary rise methid

Answer 1

Answer:

One method to measure the surface tension of a liquid is to measure the height the liquid rises in a capillary tube.

Explanation:

By setting the two forces above equal, we find the surface tension to be: ... The accepted value of the surface tension of water in air at 20° C is γ = 0.073 J/m².

Answer 2

Answer:

The capillary rise method is a test conducted to determine the surface tension of a liquid or the contact angle of liquid with soil or pipe material. ... Capillary rise takes place due to the combined effect of cohesive and adhesive forces that cause liquids to rise up in tubes of very small diameter.
