Answer:
In a solid, the molecules are tightly packed in neat rows and they vibrate quickly. Solids have a definite shape and volume. In a liquid, the molecules have more energy and they move around more freely. Liquids have a definite volume but they don't have a definite shape. The molecules in gases are spread apart and move very freely with very much energy. Gases do not have a definite shape or volume.

The description of the arrangement of water molecules and their motion in a solid, liquid and gas form and how they differ in each form is as follows:
Solid state is characterized because the molecules that compose it are very close together by a network of covalent bonds and in more or less fixed positions; this makes the distance between the particles practically unchanged.
This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.
In the liquid state, the forces between the particles are weaker than in the solid state, which allows the particles to have some freedom of rotation and translation, due to mobile ions.
Besides the vibration; they can slide over each other and maintain a constant mean distance between them without being fixed.
For this reason, liquids, unlike solids, take variable forms, depending on the container that contains them and they can also flow easily.
Their similarity to solids is based on the fact that, like the solids, they are difficult to compress and have constant volume.
In the gaseous state the attractive forces are practically zero and the particles acquire a total mobility of vibration, rotation and translation,
Being the distance between the molecules much greater than the one that they have in solid or liquid state and, in addition, variable at all times.
Gases, unlike solids and liquids, can be easily compressed or expanded and also take the shape of the container that contains them, occupying the entire available volume.
Therefore, the intensities of the interactions or cohesion forces of water molecules are not the same in solids, liquids and gases, the effects of movement and interaction on the arrangement of the particles are opposed, resulting in different states of aggregation.
