Question

which list includes only physical properties?
o density, reactivity, and conductivity
o boiling point, conductivity, and color
o color, odor, and flammability
o flammability, reactivity, and ductility

Explanation:

Physical properties can be observed or measured without changing the substance's chemical identity. Boiling point is a physical property related to state - change temperature, conductivity is the ability to conduct heat or electricity, and color can be observed visually without altering the substance chemically. Reactivity and flammability are chemical properties as they involve chemical changes.

Answer:

boiling point, conductivity, and color
