Matter in Our Surroundings explains the basic concept of matter and its different forms. Everything around us that occupies space and has mass is called matter. Matter is made up of very small particles that are constantly moving and have spaces between them. These particles attract each other, which helps matter maintain its form. Matter mainly exists in three states: solid, liquid, and gas. Changes in temperature and pressure can cause matter to change from one state to another, such as melting, freezing, evaporation, and condensation. Understanding matter helps us explain many everyday phenomena and physical changes in our surroundings.
