State of matter that has no shape or own volume, and cohesion is so weak that disperses easily in the environment by its low density. The term was created by chemical flamenco Joannes Baptista Van Helmont in the 17TH century, from the latin chaos ("spirit light, without limitation") which comes from the Greek x3C7; x3B1; x3BF; x3C2; ("empty, primeval abyss without order").
