The closer your molecules are, the harder you are. Solids also can hold their own shape. A rock will always look like a rock unless something happens to it. The same goes for a diamond. Even when you grind up a solid into a powder, you will see little tiny pieces of that solid under a microscope. Liquids will move and fill up any container. Solids like their shape. Solids can be made up of many things. They can have pure elements or a variety of compounds inside. When you get more than one type of compound in a solid it is called a **mixture**. Most rocks are mixtures of many different compounds. Concrete is a good example of a manmade mixture. ​ __LIQUIDS__ The second state of matter is liquid. What is a liquid? Water is a liquid. Your blood is a liquid. Liquids are an in-between state of matter. They can be found in between the solid and gas states. They don't have to be made up of the same compounds. If you have a variety of materials in a liquid, it is called a solution. A liquid will fill up the shape of the container it is in. If you pour some water in a cup, it will fill up the bottom of the cup first and then fill the rest. The water will also take the shape of the cup. It fills the bottom first because of **gravity**. The top part of a liquid will usually have a flat surface. That flat surface is because of gravity too. Putting an ice cube (solid) into a cup will leave you with a cube in the middle of the cup; the shape won't change until the ice becomes a liquid.== =Gases:= =The third state of matter is __GAS__ .Gas is the only state of matter which can be squashed into smaller volume.Smoke is one of the only gases you can see.Gas cannot flow but it can spread easily.The humans produce stinks a bit,that gas is called methane,cows produce it too.Gas can hold lots of energy.= = = =Gas can fill any size and shape.Gases are in different packs of atoms.=
