- Fingers are wetted while counting the currency notes - Adhesive force is greater than cohesive force
- Water will not stick to the colocasia leaf - Cohesive force is greater than adhesive force
- We can write on the black board using chalk - Adhesive force is greater than cohesive force
- Water drops are in spherical shape - Cohesive force is greater than adhesive force
- Adhesive force is the type of force of attraction which acts between molecules of different types.
- While cohesive force is the type of force of attraction that acts between molecules of same types which holds them together.
- There are a lot of examples in daily life from which these forces can be understood such as water sticking to the glass, rain drops sticking on the window pane, etc.
