Physics Question on Surface tension
Surface tension does not vary with
A
temperature
B
concentration
C
size of the surface
D
vapour pressure
Answer
size of the surface
Explanation
Solution
Surface tension is the force exerted on the surface of the liquid by the molecules which are down the surface, which manage to draw the surface molecules inside the bulk. Cohesive force is responsible for surface tension. It is independent of the size of the surface.
