Liquids have comparatively low inter-molecular force than solid.Some of the examples of liquids are alcohol, water, oil, milk, etc. Whereas, liquid can also be converted into solid. Under suitable conditions and temperature, the state of the solid can be changed into a liquid. Liquids can expand more comparative to solid under the influence of thermal expansion. The inter-molecular space between the molecules of liquid allows them to flow. The liquids have low inter-molecular force in between the molecules as compared to solids but higher than that of gases. Liquids take the shape of the container in which it is kept and also occupies space. The liquid is a state of matter that does not have a fixed shape but has fixed volume. Hence, their shape cannot be changed easily but can be broken down under the influence of force.

Most of the solids are rigid in nature.

As the molecules of solids are highly packed so they do not flow.

They have really high density and are heavy in nature.

Solids have high inter-molecular force.

Some of the examples of solid are sugar, salt, sand, stone, wood, etc. Whereas, some of their states can be changed into a liquid with an increase in temperature. They cannot be compressed easily under normal conditions. Solids show the least expansion as compared to other states of matter due to their rigid nature. As the molecules are tightly packed they do not flow and acquires high density. The solids have tightly packed molecules as a result have high intermolecular force. It has a rigid structure hence does not takes the shape of the container, unlike liquid or gases. The solid is a state of matter that has a fixed shape and definite volume. The matter is defined as a substance that has mass and occupies a certain space or has volume.
