What Are the Forms of Matter?
The world and everything in it are made up of three states of matter. These states of matter include solid, liquid, and gas. Solids have a fixed shape, and the molecules are tightly packed. The car you ride in, your stationery box, smartphone, and water bottles are all forms of solids. They do not change shape, and their volume stays the same. Liquids take the shape of the container and do not have a shape of their own. Also, liquids can easily flow. The molecules of a liquid are not so closely packed and can slide over each other with ease. Water, soft drinks, juices, and paint are all forms of liquids. Gas, the third state of matter, are made of widely spaced molecules. Gases can be compressed and take up the entire space in the container. Air, ammonia, etc. are all forms of gases.
