Tips and Tricks on Mechanics Of Solids And Fluids




Surface tension decreases with impurities. In case of soluble impurities surface tension may increase or decrease depend upon the nature of impurity. Highly soluble impurities like salt increase surface tension Sparingly soluble impurities like soap decreases surface tension. Surface tension depends only on the nature of liquid and is independent of the area of surface or length of line considered.
