what is the application of surface tension
Answers
Walking on water: Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface. Floating a needle: A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water
⚘ The Application of Surface Tension is :
❀ Formation Of Drops ;
☘ Due to the surface tension, a small quantity of liquid free from external forces always takes up a spherical shape.
☘ The molecules lying on the outer surface of the liquid drop will experience resultant force you acting inward and perpendicular to the surface of liquid drop.
☘ Therefore, the pressure inside the drop is greater than the pressure outside it.
☘ This excess pressure inside the drop will provide a force acting outward perpendicular to the force which balances the force due to surface Tension.
☘ For Example ; Raindrops are spherical in shape due to surface tension.
