1. Section 1 What Is Matter? Chapter 3 Matter Matter is anything that has mass and takes up space. Matter can be described in terms of its volume, mass, and weight.

2. Section 1 What Is Matter? Chapter 3 Matter and Volume The amount of space that an object occupies is known as volume. Volume is a measure of the size of a body or region in three-dimensional space. The liter (L) is the SI unit for volume.

3. Section 1 What Is Matter? Chapter 3 Matter and Volume, continued The meniscus is the curve at a liquid’s surface. Volume should be measured from the lowest point of the meniscus.

4. Section 1 What Is Matter? Chapter 3 Matter and Volume, continued Cubic meters (m3) and cubic centimeters (cm3) are the units used for the volume of solid things. To find the volume of regularly shaped objects, use formulas. For example, to find the volume of a cube use Length x Width x Height.

5. Section 1 What Is Matter? Chapter 3 Matter and Volume, continued The process of pushing water out of the way is called displacement. To find the volume of an irregularly shaped solid object, use water displacement. The volume of water displaced by an object is equal to the object’s volume.

6. Section 1 What Is Matter? Chapter 3 Matter and Mass Mass is a measure of the amount of matter in an object. The terms mass and weight do not mean the same thing. Weight is a measure of the gravitational force on an object. An object’s weight can change depending on its location in the universe.

7. Section 1 What Is Matter? Chapter 3 Matter and Mass, continued The SI unit for mass is the kilogram (kg). Weight is expressed in newtons (N).
