Let's evaluate each statement based on scientific principles:
1. **The wood burning in the campfire has a chemical property for being combustible.**
**True.** Combustibility is a chemical property of materials that indicates their ability to burn in the presence of oxygen.
2. **The marshmallows are undergoing a physical change only.**
**False.** While the marshmallows may initially undergo physical changes (like melting and browning), they also undergo chemical changes, like caramelization and Maillard reactions, as they toast.
3. **The smoke coming off of the fire, wood, and toasted marshmallows is a form of matter.**
**True.** Smoke is made up of tiny particles and gases and is considered a form of matter.
4. **The roasting marshmallows are undergoing a chemical change as they toast.**
**True.** The toasting process involves chemical changes due to the breaking down of sugar and other compounds, leading to the browning and flavor changes associated with roasting marshmallows.
To summarize:
1. True
2. False
3. True
4. True
