Final answer:
Burning wood is an example of a chemical change because it produces new substances, such as carbon dioxide and water vapor, which cannot be reversed, making it the correct answer.
Step-by-step explanation:
To determine which of the listed options demonstrates a chemical change, we need to understand the difference between physical and chemical changes. A physical change is one where the form of matter is altered, but not its chemical identity. Examples include melting, freezing, and dissolving. A chemical change, on the other hand, results in the formation of new chemical substances with different properties.
In the examples provided:
- Melting ice is a physical change.
- Cutting paper is a physical change.
- Burning wood is a chemical change because it produces new substances like carbon dioxide and water vapor, and cannot be reversed.
- Dissolving salt is a physical change because the salt can be recovered by evaporating the water.
Therefore, the correct answer is c) Burning wood, as it results in a chemical change.
