Question

volume of the two liquids.
Example 3.4. At 293 K, 10-2 dm of water formed 29 drops and the same volume of a
organic liquid formed 86 drops in the same stalagmometer. Density of the organic liquid
is 0.7 g cm. If the surface tension of water is 7.2 x 10-2 Nm', what would be the
surface tension of the organic liquid?​

Answer 1

Explanation:

'drop') is one of the most common methods for measuring surface tension. The principle is to measure the weight of drops of a fluid of interest falling from a capillary glass tube, and thereby calculate the surface tension of the fluid. We can determine the weight of the falling drops by counting them.
