State of Matter

Everything around us is made up of matter, which exists in different states. The three primary states of matter are solid, liquid, and gas. Understanding the characteristics and behavior of each state is an essential concept in science.

Solid

A solid is a state of matter with a definite shape and volume. Particles in a solid are tightly packed together and vibrate in place. They have a fixed position and do not move around freely. Solids are not easily compressed and tend to maintain their shape unless acted upon by an external force.

Liquid

Liquids have a definite volume, but they take the shape of their container. The particles in a liquid are not as tightly packed as in a solid, allowing them to move around each other. This is why liquids can flow and be poured. Like solids, liquids are not easily compressed.

Gas

Gases have neither a definite shape nor a definite volume. The particles in a gas move freely and are much farther apart compared to solids and liquids. Gases can fill any container they are placed in and are easily compressed. They also have the ability to expand to fill the space available to them.

Changes in State

Matter can change from one state to another through the processes of melting, freezing, evaporation, condensation, and sublimation. These changes are caused by adding or removing energy from the system.
