Question

What is the effect of temperature on angle of contact?

Answer 1

angle of contact is inversely proportional to temperature.
mathematically ,
if we assume angle of contact is $\theta$, and temperature is $T$
then relation between $\theta$ and T is given by , $\theta\propto\frac{1}{T}$

it means, if the temperature increases, angle of contact decreases due to decrease cohesive force and if the temperature decreases, angle of contact increases due to increase cohesive force .

Answer 2

Answer:

angle of contact is inversely proportional to temperature.

mathematically ,

if we assume angle of contact is \thetaθ , and temperature is TT

then relation between \thetaθ and T is given by , \theta\propto\frac{1}{T}θ∝T1

it means, if the temperature increases, angle of contact decreases due to decrease cohesive force and if the temperature decreases, angle of contact increases due to increase cohesive force
