Detailed explanation-1: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-2: -Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself. and adhesion means that water likes to stick to other things.

Detailed explanation-3: -A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs-shared and unshared-repel each other.

Detailed explanation-4: -Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.

Detailed explanation-5: -Hydrophobic and Hydrophilic : Many molecules can be described as being either hydrophobic or hydrophilic. ‘Hydro’ means water, while ‘phobic’ means fearing and ‘philic’ means loving. Hydrophobic molecules are afraid of, or repelled by water. Hydrophobic molecules, on the other hand, happily interact with water.
