cohesion-- Water molecules stick to each other.
adhesion-- Water molecules stick to other molecules.
Water is a polar molecule because of oxygen is more electronegative.
Hydrogen bonds create surface tension and result it water's cohesive and adhesive properties.
Hydrophobic = repel water
Hydropholic = affinity for water. ......
hahaha XD

ViviWater is adhesive due to its polar nature and hydrogen bonding. The oxygen atom in water has a slight negative charge, while the hydrogen atoms have a slight positive charge. This polarity allows water molecules to attract and stick to other molecules that also have polar or charged regions, such as surfaces with hydroxyl (OH) groups.

What is responsible for the attraction between water molecules?
Water molecules are attracted to each other by 'cohesive force'. It is the force that holds a droplet of water together in a raindrop, or in a semi-spherical shape if dripped onto glass. Water is also affected by ' adhesive force' which causes the droplet on glass to adhere (stick ) to the glass as well. In a thin glass tube the adhesive force makes the water move upwards.
What is adhesive force?
Adhesive force is the attraction between molecules of different substances. It allows substances to stick together, such as water sticking to a glass surface. Adhesive force is important in processes like adhesion, where two different materials are held together.
What makes bandages stick?
Bandages stick to the skin because of the adhesive material on one side of the bandage. This adhesive is specially designed to create a bond with the skin's surface, providing a secure hold. The adhesive is non-toxic and hypoallergenic to prevent any irritations.
What are the adhesive used in plaster of Paris?
The adhesive used in plaster of Paris is water. When water is added to plaster of Paris powder, a chemical reaction occurs that causes the powder to transform into a thick paste that can then be applied to a surface before hardening.
What special abilities do water molecules have because they are polar?
Water molecules have special abilities due to being polar that include cohesive forces, where water molecules are attracted to each other, allowing water to form droplets; adhesive forces, where water molecules are attracted to other substances; and high surface tension, allowing some insects to walk on water.
