what are adhesive and cohesive forces

Cohesive forces are the attractive forces between molecules of the same substance. These forces are responsible for the bulk property of liquids resisting separation. For example, water has strong cohesive forces, which cause it to form droplets. On the other hand, adhesive forces are the attractive forces between molecules of different substances. They cause liquid drops to cling to surfaces such as window panes. Adhesive forces are also responsible for phenomena such as capillary action and surface tension. Both cohesive and adhesive forces play a significant role in determining the behavior of liquids in various situations
