Matter is anything that takes up space in the universe. It has general properties like mass and volume, and specific properties like color and density. There are two types of changes in matter: physical changes, which do not change the mass or type of matter, like changes in shape or state; and chemical changes, which produce new substances when two or more react. Pure substances are made of one type of matter, while mixtures contain different types that can sometimes be separated.
