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

Explanation:

property (involves chemical change).

• Option2: Boiling point, conductivity, color are all physical properties (no chemical change needed to observe/measure).
• Option3: Flammability is a chemical property (involves combustion, a chemical reaction).
• Option4: Flammability and reactivity are chemical properties.
