Surface tension is what allows objects with a higher density than water such as razor blades and insects .
Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects to float on a water surface without becoming even partly submerged.
An iron needle floats on the surface of the water because of surface tension. Not all substances can float on water due to surface tension. Only objects whose weight is lesser than the force due to surface tension will float.
Because of the relatively high attraction of water molecules to each other through a web of hydrogen bonds, water has a higher surface tension (72.8 millinewtons (mN) per meter at 20 °C) than most other liquids. Surface tension is an important factor in the phenomenon of capillarity.
पानी की सतह पर हल्का होने के कारण सुई पानी के ऊपरी सतह की सरफेस टेंशन को नहीं तोड़ पाती है और वह उसकी सतह पर तैरती है
