Detailed explanation-1: -Water is relatively light, but has very strong hydrogen bonding. Hydrogen bonding is the strongest intermolecular force and will act to pull water molecules closer to each other. The result is a dense liquid that does not easily transition into a less dense gas.

Detailed explanation-2: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).

Detailed explanation-3: -Its hydrogen bonding causes its many unique properties, such as having a solid form less dense than its liquid form, a relatively high boiling point of 100 °C for its molar mass, and a high heat capacity.

Detailed explanation-4: -Answer and Explanation: Two properties of water that result from the polar bonding between its molecules are cohesion and adhesion. These properties cause water molecules to ‘stick’ to each other and to be attracted to other polar molecules.
