Surface tension can be defined as the tangential force per unit length acting perpendicularly to the line drawn in the surface of the liquid.
Read More2021-4-27 · Surface tension is the tendency of a liquid’s surface to resist rupture when placed under tension or stress. If a small object is placed carefully on its surface, the tension created by the hydrogen bonds in the water can often prevent the object from sinking. It helps creatures to walk on the water.
Read MoreThe surfactants combine with a water molecule and lower its original surface tension. Chemical additions- It changes the characteristics of surface tension. When some random chemical is mixed with a substance, it changes the surface tension. A surfactant in water is the best example of chemical addition.
