Question

question 2 / 14
is the following a chemical or physical property of matter?
luster
(how shiny something is)
a. chemical
b. physical

Explanation:

Physical properties of matter are characteristics that can be observed or measured without changing the substance's chemical identity. Luster (how shiny something is) is a physical property because it describes the appearance of a substance and does not involve a chemical reaction or change in the substance's chemical composition. Chemical properties, on the other hand, relate to how a substance interacts with other substances to form new substances (e.g., flammability, reactivity). Since luster is an observable physical characteristic, it is a physical property.

Answer:

B. physical
