This represents a solids atom makeup. The atoms in a solid are all really close together and are always vibrating. They have little to no room at all for movement. They form a definite shape and volume. A solid can be anything from a rock to a television. To form a solid from liquid or gas, you must take away energy. To melt a solid, you must add energy.
This picture represents the atom makeup of a liquid. As you can see, the atoms have more elbow room, and will spread out if possible. It has no definite shape, but it does have a definite volume.
To make a liquid a solid, you must take away energy. To make it a gas, you must add energy.
This picture represents how gas atoms move about. They have no definite shape, no definite volume, no definite anything. They move about freely because they have so much room. To make gas a liquid or a solid, you must take away energy.
This represents plasma. The blue streaks of energy are plasma. It is extremely fast, extremely dangerous, and is rarely found on earth. You can find plasma in stars, the sun, and almost everywhere! Its is the most common state of matter in the universe.
Personally, I think it's great that we're getting more in depth with solids, liquids, gasses, and plasma. Who knew there was more to it?
