We were taught in school about what matter is. Look around you. The whole thing you see is matter. Can you recall the definition?
Matter is anything that has mass and volume (occupies space). From the definition of matter, let us define some terms in order for you to clearly understand what matter is. Mass is the amount of matter in an object. Keep in mind that weight is the force of gravity pulling on the object. An object's weight is dependent upon mass and gravity pulling on it. All matter takes up space. This means it has volume. For the moment, let us side-step the meaning of matter and focus on the chemist’s view: matter is what chemical substances are composed of. But what do we connote by chemical substances? How do we sort out our view of matter and its properties? These will be the area under discussion of this lesson.
