These are just a few examples of the many chemical properties of matter. Now you can better understand what a chemical property is. Remember, unlike a physical property, it is a characteristic that can only be observed as a result of a chemical reaction. For more on the subject, read about the differences between a chemical and physical change.
All rights reserved. Fire testing is done to determine how difficult or easy it will be to get a certain material to burn. Information about flammability is used in building codes, fire codes, insurance requirements, and storing, handling, and transporting highly flammable materials. These properties can be used to sort the elements into three classes: metals elements that conduct well , nonmetals elements that conduct poorly , and metalloids elements that have properties of both metals and nonmetals.
The periodic table is a table of elements that places elements with similar properties close together Figure 5. You will learn more about the periodic table as you continue your study of chemistry. Figure 5. The periodic table shows how elements may be grouped according to certain similar properties. Note the background color denotes whether an element is a metal, metalloid, or nonmetal, whereas the element symbol color indicates whether it is a solid, liquid, or gas.
All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter. Chemical properties, such flammability and acidity, and chemical changes, such as rusting, involve production of matter that differs from that present beforehand.
Measurable properties fall into one of two categories. Extensive properties depend on the amount of matter present, for example, the mass of gold. Intensive properties do not depend on the amount of matter present, for example, the density of gold.
Heat is an example of an extensive property, and temperature is an example of an intensive property. Considering that mass and volume are both extensive properties, explain why their ratio, density, is intensive. Selected Answers 2. The value of an extensive property depends upon the amount of matter being considered, whereas the value of an intensive property is the same regardless of the amount of matter being considered.
Being extensive properties, both mass and volume are directly proportional to the amount of substance under study. Skip to main content. A chemical change always produces one or more types of matter that differ from the matter present before the change. The formation of rust is a chemical change because rust is a different kind of matter than the iron, oxygen, and water present before the rust formed.
The explosion of nitroglycerin is a chemical change because the gases produced are very different kinds of matter from the original substance. Other examples of chemical changes include reactions that are performed in a lab such as copper reacting with nitric acid , all forms of combustion burning , the ripening of fruits, and food being cooked, digested, or rotting.
