The characteristics that enable us to distinguish one substance from another are called properties. Identify properties of matter as extensive or intensive.Distinguish between physical and chemical properties.Identify properties of and changes in matter as physical or chemical.ěurning of the wood results in the formation of ash, carbon dioxide, and water.By the end of this section, you will be able to:.Ĝooking and rusting are types of chemical changes as they produce substances with different chemical compositions.Ě chemical change might also result in the formation of a precipitate or a cloudy or white-colored material after the substances are dissolved and mixed.Some examples of the chemical change are mentioned below: The reacting species of the reaction are known as reactants, and the species that are formed after the reaction are known as products. The chemical changes are also termed as chemical reactions. The burning of a compound is a chemical reaction in which high temperature is provided to the reaction in the presence of oxygen. The change in the oxidation state of species is also its chemical property. ěoth oxidation and hydrolysis are chemical reactions as substances undergo chemical changes in both cases.The energy released during the combustion of the compound in the presence of oxygen is known as the heat of combustion.Some of the chemical properties of matter are mentioned below: Chemical change involves the formation of a new substance. Therefore, the chemical change affects the chemical properties of substances as well as their internal structure. The internal structure of the substance must be affected by chemical change. In other words, the appearance or quality can be established by the change in the chemical identity of matter or substance.Ĭhemical properties cannot be observed by touching or viewing the matter or substance. The chemical property is the property of the material or substance that can be evident during the chemical reaction. The changing of phases is a physical change as the nature of the.The cutting of trees is a physical change as the composition of the.The breaking of a pencil is a physical change as the composition of.Some examples of the physical change are mentioned below: There are three main states of matter that are solid, liquid, and gas. These changes are directly related to the physical properties of the matter. In other words, the same compound or element will be present before and after the reaction or the change. The change that takes place without changing the chemical composition of the matter is termed as a physical change. The melting point is the temperature at which a substance starts melting and is The density of the matter is classified as an intensive property. The volume of the matter is classified as an extensive property. The boiling point is the temperature at which a substance starts boiling and Mass of the matter is classified as an extensive property. The color of the matter is classified as an intensive property. Some of the physical properties of matter are classified as extensive and intensive properties as mentioned below: No new substance is formed in a physical change. It does not affect the chemical properties of substances. The physical change affects either the state or the form of the substances. The classification of the physical properties is based on the size of the substances. These properties are often described in terms of their extensive and intensive properties. Physical properties are used to describe and observe the nature of substances.
