The cohesive and adhesive forces in a liquid are identical when the angle of contact between the liquid and the container is 90° (degrees). 

Cohesive force is the attraction between similar atoms while adhesive force is the attraction between distinct atoms.

It means that the liquid does not spread or retract on the container's surface. This contact angle is also known as the "contact angle."

The adhesive force between the liquid and the container is equal to the cohesive force within the liquid in this case.
