Surface tension is the property of water which allows for some lightweight insects to walk on top of a pond and not fall in. The molecules of water are held together by cohesive forces. The molecules of water present below the surface experience this cohesive force from all the directions, whereas the water molecules present on the surface experience a downward pull, as the force is not balanced. This leads to the concaving of the water surface inside a small tube.
the specific gravity of pure sulfuric acid is---------> approximately 1.835 g / cm3
the specific gravity of water is -------------------- >1.000 g / cm3.
The electrolyte, that is, the dissolution of sulfuric acid in water, is usually at a rate of 36% acid, so that, in a fully charged element, we can deduce the electrolyte density, is 1.295 g / cm3. (see attached table)
The specific gravity is actually the difference in the weight of water compared to a specific fluid. It is measured with a hydrometer
