Q. In the glass capillary tube, the shape of the surface of the liquid depends upon

only on the cohesive force of liquid molecules

only on the adhesive force between the molecules of glass and liquid

only on relative cohesive and adhesive force between the atoms

neither on cohesive nor on adhesive force

$cos θ = \frac{T _{S A} - T _{S L}}{T _{L A}}$
From this diagram, angle of contact depends on surface tension due to solid, liquid and gas(air) all the three

Q. In the glass capillary tube, the shape of the surface of the liquid depends upon

only on the cohesive force of liquid molecules

only on the adhesive force between the molecules of glass and liquid

only on relative cohesive and adhesive force between the atoms

neither on cohesive nor on adhesive force

cosθ=TLA​TSA​−TSL​​ From this diagram, angle of contact depends on surface tension due to solid, liquid and gas(air) all the three

$cos θ = \frac{T _{S A} - T _{S L}}{T _{L A}}$
From this diagram, angle of contact depends on surface tension due to solid, liquid and gas(air) all the three
