Solids are also referred to as condensed phases. The particles of a solid have little free space between one another. Particles are also tightly packed together and normally in a regular pattern. Particles of a solid can't move or slide past each other. Solid's particles vibrate or jiggle, but never move nor slide. Sources: http://www.chem.purdue.edu/gchelp/liquids/character.html

There are three states of matter which include a solid, gas, and a liquid. A solid has it's own definite shape and volume. Which means it doesn't take the shape of it's container. Solids particles are packed tightly in an orderly manner. Since you can't squeeze a solid to make a smaller volume, it's considered as an incompressible. When heated it slightly expands. Some solids, such as ice, can be dissolved in water or a liquid. Salt is an example of a solid at room temperature.

Plasma is an ionized gas. "A gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist." Most space plasmas have a very low density. "In effect a plasma is a cloud of protons, neutrons and electrons where all the electrons have come loose from their respective molecules and atoms, giving the plasma the ability to act as a whole rather than as a bunch of atoms." Plasmas are a very common state of matter, they make up more than 99% of our visible universe and most not being visible. Plasma mkaes up the sun and the core of stars. On earth, plasma occurs in lightning.

A solid is a state of matter that has particles that vibrate in place and don't move. Unlike a gas or liquid, a solid has a fixed shape, and unlike a gas, a solid has a fixed volume. Sources: http://science.yourdictionary.com/solid

There are six noble gases in group 18 of the periodic table. The gases are Helium, Neon, Argon, Krypton, Xenon, and Radon. In the 1960'sthey were considered to be inert gases, because of their compounds. These elements are in order by increasing atomic mass. These elements are colorless and odorless. Gases have no defined shape, all so the particles and far from one another.

Plasma is a gaseous mixture of high-energy electrons and ions that activates tiny fluorescent tubes in chambers called pixels.

I'm sort of confused, because the packet tell me to post here, but im in Mrs. Uy's class, and on her website it doesn't have a spot for this.

“A solid is one of the three commonly recognized states of matter. It has both a definite shape and a definite volume. The molecules of a solid, like those of a liquid, are very close together, but whereas the molecules of a liquid are free to move around, those of a solid have less thermal energy and are held fixed in their places by intermolecular forces. Their only movement is a vibration about a fixed position. Solids are of various types. Some solids, e.g., chalk and clay, have no regular structure and are called amorphous. .Properties in which solids differ from one another include density, hardness, malleability, ductility, elasticity, brittleness, and tensile strength.”

Solids are tightly packed molecular bundles. The bonding's are so strong that the particles can not move, but can only vibrate at an alarmingly fast rate. Which in turn gives a solid a stable, definite shape, and a definite volume. Force must be applied for a solid to be changed. Crystalline solids are packed in a tight orderly manner. Ice has different forms of crystallized patterns. Solids can be turned into liquid by melting, and into gasses through sublimation. Sublimation is when a material is suddenly turned from a solid into a gas.
