On Earth 1 N = 100 grams (g) What Is Matter? Matter and Mass Section 1 The Difference Between Mass and Weight Weight is a measure of the gravitational force exerted on an object. Measuring Mass and Weight The SI unit of mass is the kilogram (kg), but mass is often expressed in grams (g) and milligrams (mg), too. Weight is a measure of gravitational force and is expressed in the SI unit of force, the newton (N).

What Is Matter? Inertia Section 1 What Is Inertia? Inertia is the tendency of an object to resist a change in motion. Mass: The Measure of Inertia Mass is a measure of inertia. An object that has a large mass is harder to get moving and harder to stop than an object that has less mass.

Physical Properties Physical Properties Section 2 Identifying Matter You use physical properties every day. For example, physical properties help you determine if your socks are clean (odor), if your books will fit into your backpack (volume), or if your shirt matches your pants (color). Density Density is the amount of matter in a given space, or volume. Liquid Layers If liquids are different densities are carefully poured into a cylinder, the liquids will separate into layers because of the differences in density.

Physical Properties continued Section 2 Physical Properties Physical Properties continued Density of Solids Knowing the density of a substance can tell you if the substance will float or sink in water. If the density of an object is less than the density of water, the object will float. Solving for Density Density equals mass divided by volume. Using Density to Identify Substances Density is a useful physical property for identifying substances. Each substance has a density that differs from the densities of other substances.

Chemical Properties Chemical Properties Section 3 Comparing Physical and Chemical Properties Physical properties are easy to observe. Chemical properties, however, aren’t as easy to observe. For example, you can see that wood is flammable only while it is burning. Characteristic Properties The properties that are most useful in identifying a substance are characteristic properties.These properties are always the same no matter what size the sample is.

Chemical Changes and New Substances Section 3 Chemical Properties Chemical Changes and New Substances What Happens During a Chemical Change? A chemical change happens when one or more substances are changed into new substances that have new and different properties. Examples of chemical changes are shown on the next slide. Signs of Chemical Changes Signs that indicate a chemical change include a change in color or odor, production of heat, fizzing and foaming, and sound or light being given off. Matter and Chemical Changes Chemical changes change the identity of the matter involved.

Physical Versus Chemical Changes Section 3 Chemical Properties Physical Versus Chemical Changes A Change in Composition Physical changes do not change the composition of a substance. But chemical changes do alter the composition of a substance. Reversing Changes Many physical changes are easily reversed.They do not change the composition of a substance. But composition does change in a chemical change. So, most chemical changes are not easily reversed.
