What is the surface tension of water?
do all liquids have the same surface tension? why?

At the interface of two fluids, there is a difference in pressure. This leads to the existence of a surface force, the surface tension, that shapes the fluid.

The surface tension of water is roughly 72 dynes/cm, 

However, that is highly dependant on the characteristics of the considered material (physical and chemical), and thus all fluids (and thus liquids) do not have the same surface tension.

Without a large portion of us never paying consideration on it, surface tension is acting surrounding us, all around and constantly, influencing our day by day life in various ways. Truth be told it is surface tension that keeps the billions of cells in our body utilitarian, guaranteeing the best possible association of their biomolecules, into films and different sorts of cell organelles. Surface tension is a genuinely major property of water, making it a perfect medium taking into account for life as we probably aware it is existing. Speaking of a better effectively available scale, well known to every one of us, it is surface pressure or tension that makes water drops circular.
