Water molecules are linked by hydrogen bonds.

Adhesion occurs when liquid molecules are attracted to the surface of a solid like a container, causing the liquid to stick to the solid. Cohesion, on the other hand, is the attraction between the liquid molecules themselves, causing them to stick together. In the case of a meniscus, adhesion between the liquid and solid container causes the liquid to curve up or down, while cohesion helps keep the liquid molecules together to form a curved surface.
The force of attraction between molecules below the surface of a liquid is called cohesive force. This force creates an inward pull, causing the liquid molecules to stick together and form a well-defined surface.
the bonds between the water molecules are broken
In the liquid phase, the most prevalent attractions between molecules of HF are hydrogen bonding interactions. These interactions occur between the hydrogen atom in one HF molecule and the fluorine atom in another HF molecule, forming a strong dipole-dipole bond. Additionally, van der Waals forces also contribute to the overall attraction between HF molecules in the liquid phase.
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
Water molecules cohere to form a liquid due to hydrogen bonding between the molecules. This hydrogen bonding leads to a net attractive force between the molecules, allowing them to stay close together in a liquid state.
The forces between molecules in steam are weaker than the forces between molecules in liquid water. In steam, molecules are far apart and move freely, resulting in weak intermolecular forces. In liquid water, molecules are closer together and have stronger intermolecular forces due to hydrogen bonding.

liquid molecules forming a gas and gas molecule forming a liquid are equal in number

It has a different amount of space between molecules

A volatile liquid is easy to vaporize because there are weak intermolecular attractions between its molecules. A nonvolatile liquid is difficult to vaporize because there are strong intermolecular attractions between its molecules.
At the molecular level, the main difference between a solid and a liquid is the arrangement and movement of molecules. In a solid, molecules are tightly packed together in a fixed position, vibrating in place. In a liquid, molecules are more loosely packed and can move around each other, allowing the liquid to flow.
The molecules in a liquid are densely packed than in a gas. The shorter distance between the molecules allows the energy to transfer more efficiently between molecules, therefore allowing more heat to pass between them.
