Detailed explanation-1: -Water droplets join together as they run down the windshield of the car. surface tension.

Detailed explanation-2: -A water drop is composed of water molecules that like to stick together-an example of the property of cohesion.

Detailed explanation-3: -Cohesion is a property of water in which water molecules bond to other water molecules. This results in surface tension and the formation of raindrops. Adhesion is the ability of water molecules to bond with other molecules. This allows water to stick to windows and other substances.

Detailed explanation-4: -Water droplets are formed after condensation of water vapour. These droplets come together and clump forming clouds.

Detailed explanation-5: -In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-gas (water-air) interface, although there is no more room in the glass.
