< BackNext >PreviewMain Section 1 What Is Matter? Chapter 2 Matter and Mass The Difference Between Mass and Weight Weight is the measure of the gravitational force exerted on an object. The more mass an object has, the greater the gravitational force on the object and the greater the object’s weight. Measuring Mass and Weight The SI unit of mass is the kilogram (kg). Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).

< BackNext >PreviewMain Section 1 What Is Matter? Chapter 2 Inertia What Is Inertia? Inertia is the tendency of an object to resist a change in motion. Mass: The Measure of Inertia An object that has a large mass is harder to move and harder to stop than an object that has less mass. The reason is that the object with the large mass has greater inertia.

< BackNext >PreviewMain Section 2 Physical Properties Chapter 2 Physical Properties, continued Identifying Matter You use physical properties to identify matter. Density Density is the amount of matter in a given space, or volume. The two balls below have different densities.

< BackNext >PreviewMain Section 2 Physical Properties Chapter 2 Physical Properties, continued Liquid Layers The graduated cylinder below contains six liquids. Each liquid is a different density so the liquids form layers. Density of Solids Knowing the density of a substance can also tell you what kind of substance it is.

< BackNext >PreviewMain Section 2 Physical Properties Chapter 2 Physical Properties, continued Solving for Density To find an objects density (D), first measure its mass (m) and volume (V). Then use the following equation: D = m/V

< BackNext >PreviewMain Section 3 Chemical Properties Chapter 2 Describe two examples of chemical properties. Explain what happens during a chemical change. Distinguish between physical and chemical changes. Objectives

< BackNext >PreviewMain Section 3 Chemical Properties Chapter 2 Chemical Properties Comparing Physical and Chemical Properties You can observe physical properties without changing the identity of the substance. Chemicals properties are more difficult to observe. Characteristic Properties The properties that are most useful in identifying a substance are characteristic properties.

During a chemical change a substance changes chemical properties. Signs of Chemical Changes Some common signs of chemical changes includes a change in color, odor, production of heat, fizzing, and so on. Matter and Chemical Changes Chemical changes change the identity of the matter involved.
