7.2.1 - Matter & Its Properties

What is Matter?

Key Concept: Matter is anything that has mass and takes up space. Matter can be described in terms of its volume, mass, and weight.

​

​Understanding what matter is and how units are used to describe matter can help you understand the structure of the physical world.
