LIFE SCIENCE

Detailed explanation-1: -This is because the water molecules are attracted to the charged glass walls of the capillary more than they are to each other and therefore adhere to it. This type of adhesion is called capillary action.

Detailed explanation-2: -Adhesion occurs because of the polarity of water. Water molecules have an uneven sharing of electrons due to covalent bonding. This creates a negative and positive end of each water molecule. The result is that water is attracted to other molecules with opposite charges.

Detailed explanation-3: -Adhesion is the property of different molecules or surfaces to cling to each other. For example, solids have high cohesive properties so they do not stick to the surfaces they come in contact. On the other hand, gases have weak cohesion. Water has both cohesive and adhesive properties.
