Plasma is the fourth state of matter. Plasma occurs at extreme high temperatures. It is found in stars, lightning, and neon lights. Plasma is the most commonly found matter in the universe, even though its not common on earth.
In crystalline solids, the particles are arranged in a repeating, three dimensional pattern called a crystal. Some forms of crystalline solids are table salt, sugar, sand, and snow. Diamonds are also crystalline solids.
Gas is a matter that does not have a definite shape or volume.The particles in gas are much father apart than those in a liquid or solid. Gas particles move at high speeds in all direction.
Plasma is different because it can only exist in extremely high temperatures. It is not common on Earth, like the other states of matter. It is only common in the universe. Plasma is found in a lot of things in space. Plasma is not bound to one atom, so it is free. Plasma is formed by adding more heat to the molecules of gas. Eventually, the molecules are moving so fast, that they break apart from their atoms, and then they are positively charged ions, or plasma.
