Difference between Solid Liquid and Gas

Understanding the difference between Solid Liquid and Gas is important as they represent the three different states of matter. As we know everything around us is matter and it is important to understand the classification of matter; primarily into Solids, Liquids and Gases. A solid can be classified as a substance that is rigid with low inter molecular spacing and high inter molecular forces, that binds all molecules within together. Liquids on the other hand are less rigid and flows easily. They usually have the properties that enable them to flow from higher areas to lower ares. This is a unique property of liquids when compared to solids. However there are a few imperfections in solids.

Difference between Solid Liquid and Gases

Gases on the other hand have uniquely different properties compared to Solids and Liquids. Gases are primarily free flowing, with little to no intermolecular force acting between them. It is important to know the major difference between Solid Liquid and Gases.

Difference between Solid Liquid and Gases

Solids

Liquids

Gases

Highly Strong intermolecular forces between the molecules, leads to a definite volume in Solids.

The intermolecular forces are stronger than gases but weaker than solids.

The intermolecular forces are practically non existent. Thus, there is no definite volume.

Solids have a definite shape to them.

Liquids do not have a definite shape.

Gases do not have a definite shape.

The intermolecular space between solids is absent.

The intermolecular space is moderate but present.

The intermolecular space is free flowing and plenty.

The force of attraction between the molecules is incredibly high.

The force of attraction between molecules is pretty moderate.

There is no intermolecular force of attraction between the molecules.

They are incompressible.

Liquids cannot be compressed.

Gases can be compressed quite easily.
