What is matter? Matter is the fundamental component that makes up everything in the universe. From the air and water around us to the distant stars, everything is composed of matter. Let's explore this fascinating concept together.
Matter exists in three basic states: solid, liquid, and gas. In solids, particles are tightly packed and arranged in regular patterns. In liquids, particles are close together but can move around each other. In gases, particles are far apart and move freely in all directions.
Matter is composed of atoms and molecules. Atoms are the smallest units of matter, consisting of a nucleus surrounded by electrons. Molecules are formed when atoms combine together. Different combinations of atoms create different substances with unique properties.
Every substance has its own unique properties. Physical properties like color, hardness, and density can be observed directly. For example, iron is hard, heavy, and gray. Water is liquid, colorless, and flows. Oxygen is a gas that is colorless and supports combustion. These properties help us identify and classify different materials.
