Physical matter refers to anything that has mass and occupies space. This includes everyday objects like books, chairs, and water. Matter can exist in different states, such as solid, liquid, or gas, depending on temperature and pressure. For example, ice is the solid form of water, while steam is its gaseous form. Matter is made up of tiny particles called atoms, which combine to form molecules. These particles are constantly in motion, and their arrangement determines the properties of the material. Understanding physical matter is essential in fields like chemistry and physics, as it helps us comprehend the world around us.
