🔴 Surface Tension || for Class 11 in HINDI

In this Physics video in Hindi for class 11 we explained the reason behind surface tension. Surface tension is the tendency of fluid surfaces to shrink into the minimum surface area possible.
We discussed, in this Physics lecture, about the reason why, due to surface tension, water droplets on leaves are spherical, how insects can walk on water, how despite having higher density iron clip floats on water. In this Hindi video lecture you will have, with explanation, the answer of the question- what is surface tension. Surface tension is a property of liquid surface due to which liquid surface behaves like a stretched membrane. Along with a physical phenomenon surface tension is a physical quantity, so, it can be measured. If one draws an imaginary line on a liquid surface, the inter-molecular force acting across the line per unit length is defined as the surface tension of that liquid surface.

[@lalremruata544]

Sir Please reply, Sir i have read that the surface water molecules also go down inside of the liquid and their positions are again replaced by another molecules coming up from the water bottom to the surface and this process keeps on repeating. My question is sir , how is this possible at all? *How could the water molecules From inside of the water go up to the surface* while they are experiencing net downward force?. And also how could the water molecules go down inside of the water? If the net cohesive inward force doesn't pull it down?.🙏🙏

[@krishapatel9677]

At at the surface point it will feel the force downwards so it will go downward and to fill its empty place New Bubbles take place and this is microscopic turbulence process and it is going continuous in the fluid and it is the true also
