Question

write about the Factors affecting the angle of contact:​

Answer 1

$\huge\bf{\underline{\underline{Answer : -}}}$

The value of the angle of contact depends on the following factors,

i) The nature of the liquid and the solid in contact.

ii) Impurity : Impurities present in the liquid change the angle of contact.

iii) Temperature of the liquid : Any increase in the temperature of a liquid decreases its angle of contact. For a given solid-liquid surface, the angle of contact is constant at a given temperature.

Answer 2

hello

The angle of contact depends on the following factors: (a) The nature of liquid and solid. ... The angle of contact between pure water and clean glass is nearly zero. But for a slightly oily glass plate the angle of contact increases, may even become more than 90°.
