Answer:
Examples of surface tension
Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. ... Walking on water: Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface.
Explanation:
Soaps and Detergents:
Soaps and Detergents which are containing surfactants actually improve the solubility of substances such as oil, dirt, grease in water.
When any soap or detergent is added in the water, the molecules of detergent decreases the surface tension of water and penetrate in between the oil, dirt and fabric of clothes which is not possible for simple water alone. This scrubbing action helps to enter the water and detergent molecules deeper inside the fabric and makes the clothes clean and dirt, oil free.
Soap Bubbles :
Children often play with this. The formation of soap bubbles are also the action of surface tension. The soap decreses the surface tension of water that's why it can blow up and expands to be a bubble. If no soap or detergent is mixed and the surface tension is high enough it will have the tendency to be compact into a drop, then the bubble will be not formed.
Umbrella, Raincoat:
Rainproof tent materials are made of fabric that is tightly woven together, which prevents water from getting through. It has very small intermolecular gaps so that the surface tension of water will bridge the pores in the tent material.
That's why Raincoat and umbrellas are waterproof.
