Question

color change
formation of a gas
temperature change
density
melting point
boiling point
solubility
flammability
odor

you have been learning about chemical and physical properties in class. your teacher asks you to make a venn diagram that compares and contrasts physical and chemical properties. she provides you with the properties listed above to include in your diagram. which properties would you classify as chemical property only?

a flammability

b color change and odor

c melting point and boiling point

d density, temperature change, and solubility

Explanation:

To determine chemical properties only, we recall: Chemical properties describe a substance's ability to undergo chemical changes (e.g., flammability involves combustion, a chemical reaction). Physical properties (melting/boiling point, density, solubility, odor, color change in some cases) can be observed without changing the substance's chemical identity.

• Option A: Flammability is a chemical property (requires combustion, a chemical change).
• Option B: Color change can be physical (e.g., mixing colors) or chemical; odor is physical.
• Option C: Melting/boiling points are physical.
• Option D: Density, temperature change (physical process), solubility are physical.

So only flammability is a chemical property only.

Answer:

A. flammability
