Chapter 3Lesson 1

Properties of Matter• Matter- Anything that has mass

and takes up space• Everything on God’s Earth is made of

matter

Properties of matter• Characteristics of matter are called

properties

Physical Properties• Defined: Characteristics of a

substance that can be observed without changing the basic nature of the substance• Examples: Color, Odor, Shape, Mass,

Volume, Weight

Physical Characteristics• Physical characteristics can be

broken down into two categories• 1. Noncharacteristic Properties• 2. Characteristic Properties

Noncharacteristic Properties• Defined: Characteristics that can’t

be used to identify substances• Examples: Mass, shape, volume,

length

Mass• Defined: The amount of matter in

an object• Dependent upon the number of atoms

or molecules in an object

Weight• The amount of gravity exerted on

an object• Gravity- The force that pulls two

objects together because of their masses

Weight-Mass• 1. Is your mass the same on the

moon?• 2. Is your weight the same on the

moon?

Volume• Defined: The amount of space an

object takes up• Is identified in cubic meters and liters

Characteristic Properties• Properties that are unique to a

particular substance and can be used to identify that substance• Examples: Density, melting point,

boiling point

Density• Defined: The mass per unit of

volume of a substance• D=m/V (density=Mass/Volume)• Density is expressed in cubic grams

units
