The cohesion-tension model relies on the properties of water, notably cohesion and adhesion. What are cohesion and adhesion? Multiple Choice Cohesion is the tendency of water molecules to stick together and adhesion is the tendency of water molecules to interact with a surface. Cohesion is the tendency of water molecules to interact with a surface and adhesion is the tendency of water molecules to stick together. Cohesion is the tendency of water to remain in liquid form and adhesion is the ability of water to withstand changes in temperature. Cohesion is the amount of energy required to raise water by one degree and adhesion is the ability of water to dissolve many different molecules..
