Cohesive Force and Adhesive Force

Cohesive Force : The force of attraction between the molecules of same substances is called cohesive force. Cohesive Force is maximum in solids. This is why solids have a fixed shape. Cohesive Force is negligible in case of gases.



Adhesive Force : Force of attraction between the molecules of different substances is called adhesive force. Due to adhesive force, one body sticks to other.
