Explanation:

• Question 32: Flammability describes a substance's ability to undergo a chemical reaction (combustion), so it is a chemical property.
• Question 33: Density is a measurable characteristic of a substance that can be observed without changing its chemical identity, so it is a physical property.
• Question 34: Boiling point is the temperature at which a substance changes state from liquid to gas, a change that does not alter its chemical composition, so it is a physical property.

Answer:

Question 32: a. Chemical
Question 33: b. Physical
