How are chemical properties different from physical properties
Chemical properties and physical properties are two types of properties that describe the behavior and characteristics of matter. The main difference between the two is related to how they can be observed and measured.
Physical properties refer to the characteristics of a substance that can be observed or measured without changing its chemical composition. Examples of physical properties include color, odor, density, melting point, boiling point, solubility, conductivity, and hardness. These properties can be determined through direct observation or simple physical tests. Physical properties are used to identify or classify substances and can be used to predict how a substance will behave under certain conditions.
On the other hand, chemical properties describe how a substance reacts or interacts with other substances, leading to a change in its chemical composition. Chemical properties are observed when a substance undergoes a chemical reaction or transformation. Some examples of chemical properties are reactivity, flammability, toxicity, oxidation/reduction potential, and stability. Chemical properties determine how a substance will interact with other substances and can be used to predict the behavior of a substance in a specific chemical reaction.
In summary, physical properties describe the observable characteristics of a substance without changing its chemical composition, while chemical properties describe how a substance reacts or interacts chemically with other substances, leading to a change in its chemical composition.
