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.

• 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).
