The surface of liquid near the plane of contact, with another medium is in general curved. The angl… Read more Angle of Contact

Surface Energy and Surface Tension

As we have discussed that an extra energy is associated with surface of liquids, the creation of mo… Read more Surface Energy and Surface Tension

Surface Tension

You must have noticed that, oil and water do not mix; water wets you and me but not ducks; mercury … Read more Surface Tension

Viscosity and Stokes’ Law

Most of the fluids are not ideal ones and offer some resistance to motion. This resistance to fluid… Read more Viscosity and Stokes’ Law
