Solid – is a sample of matter that retains its shape and density when not confined. The constituents of a solid tend to be packed together much closer than the particles in a gas or liquid. The reason a solid has a rigid shape is because the atoms or molecules are tightly connected via chemical bonds. A solid is one of the four fundamental states of matter, along with liquids, gases, and plasma. The atoms or molecules of matter in the solid state are generally compressed as tightly as the repulsive forces among them will allow. Below are the examples of solid.

Liquid – is one of the primary states of matter. Unlike a solid, the molecules in a liquid have much greater freedom to move. The forces that bind the molecules together in a solid are only temporary in a liquid allowing a liquid to flow while a solid remains rigid. A liquid can flow, assume the shape of a container, and, if placed in a sealed container, will distribute applied pressure evenly to every surface in the container.

Gas - is one of phases of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container, even in the presence of gravity and regardless of the amount of substance in the container. If not confined to a container, gaseous matter, also known as vapor, will disperse into space. The atoms or molecules of matter in the gaseous state move freely among each other, and are, in most instances, packed more loosely than the molecule of the same substance in the solid or liquid state.
