Detailed explanation-1: -The occurrence of dipoles in water makes water a polar molecule. Thus, when water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. This is possible because of the property of polarity possessed by water molecules.

Detailed explanation-2: -The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.

Detailed explanation-3: -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-4: -Water is polar-which means it has both positive and negative ends. Water takes a lot of heat to get hot, which makes it a great coolant. This helps an organism maintain homeostasis.

Detailed explanation-5: -Hydrogen bonding of water molecules The plus end of one-a hydrogen atom-associates with the minus end of another-an oxygen atom. These attractions are an example of hydrogen bonds, weak interactions that form between a hydrogen with a partial positive charge and a more electronegative atom, such as oxygen.
