MATTERFor simpler explanation, matter is anything that takes spaces and has mass.Three States of Matter: Solid – A solid has a fixed shape and volume. The particles are tightly packed, so it stays firm like ice or a rock.➤ Example: An ice cube keeps its shape even outside the freezer.Liquid – A liquid has a fixed volume but no fixed shape. It flows and takes the shape of its container.➤ Example: Water in a glass takes the shape of the glass.Gas – A gas has no fixed shape or volume. Its particles move freely and spread out everywhere.➤ Example: The smell of perfume spreads quickly in a room.
