Section 1 What Is Matter?Chapter 3Matter

• Matter is anything that has mass and takes up space.

• Matter can be described in terms of its volume, mass, and weight.

Section 1 What Is Matter?Chapter 3Matter 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.

• The meniscus is the curve at a liquid’s surface.

• Volume should be measured from the lowest point of the meniscus.

Section 1 What Is Matter?Chapter 3Matter 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.

• 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.

Section 1 What Is Matter?Chapter 3Matter 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.

Section 1 What Is Matter?Chapter 3Matter and Mass, continued

• The SI unit for mass is the kilogram (kg).

• Weight is expressed in newtons (N).
