Question

angle of contact for the pair of pure water with clean glass is A)90⁰B) acute c)obtuse D)0⁰​

Answer 1

Answer:

The angle of contact also depends on the nature of the material of the container. For glass as the material of the container, θ is more than 90∘for mercury (obtuse) and less than 90∘for (acute) water. This also may be because mercury does not wet the material of capillary and glass wets the material of capillary.
