What are the applications of surface tension?
Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible.The cohesive forces between liquid molecules are responsible for the phenomenon.
Some notable applications of surface tension are:
● A needle placed on water can be made to float due to the surface tension of water.
● Warm water is used for washing purpose as heating increases the surface area and reduces surface tension.
● Mosquito eggs can float on water because of its surface tension.
● Toothpaste contains soap, which reduces the surface tension and helps it spread freely in the mouth.
● Surface tension prevents water from passing through the pores of an umbrella.
● Antiseptics like Dettol have low surface tension, so that they spread faster.
