Physical Property vs. Chemical Property

Physical and chemical properties are characteristics of matter that help describe and identify substances. Understanding the difference between these properties is crucial in the field of chemistry and science in general.

Physical Property

Physical properties are qualities or attributes of a substance that can be observed or measured without changing the composition of the material. Examples of physical properties include color, density, melting point, boiling point, solubility, and conductivity. These properties are intrinsic to the substance and can help in distinguishing one material from another. Physical properties are used to describe how a substance behaves under certain conditions.

Chemical Property

Chemical properties, on the other hand, describe the ability of a substance to undergo chemical changes and form new substances. These properties can only be observed when a substance undergoes a chemical reaction. Examples of chemical properties include flammability, reactivity with acids or bases, oxidation state, and toxicity. Chemical properties help determine how a substance will interact with other substances and whether it will undergo a chemical change.

In summary, physical properties describe how a substance looks, feels, or acts without changing its chemical composition, while chemical properties describe how a substance reacts with other substances to form new substances.
