What is a chemical and physical property? Is luster a chemical or physical property? (pls explain)

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

Explanation:

Physical properties can be broken down into extensive and intensive properties. Intensive properities can help you identify a substance. ... Other examples of intensive properties include density , solubility, color, luster, freezing point and malleabilityLuster. ... Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.
