Answer 1

Physical properties of matter are characteristics that can be observed or measured without changing the substance's chemical identity. Based on the options you provided, the following are considered physical properties:

- **Boiling point**
- **Mass**

On the other hand, **flammability** and **reactivity** are not physical properties; they are chemical properties since they describe the ability of a substance to undergo chemical changes.

So, you should select:
- Boiling point
- Mass
