Burning wood is an example of a chemical change.
To determine which option is an example of a chemical change, we need to understand what a chemical change is. A chemical change refers to a process in which a substance undergoes a transformation, leading to the formation of new substances with different chemical properties.
Out of the given options, "burning wood" is an example of a chemical change. When wood burns, it undergoes a chemical reaction called combustion. The heat from the fire causes the wood to react with oxygen in the air, resulting in the production of carbon dioxide, water vapor, heat, and light. The chemical composition of the wood changes during this process, forming new substances different from the original wood.
The other options mentioned - stretching a rubber band, chopping vegetables, and folding paper - do not involve a chemical reaction. These actions are physical changes, where the forms or shapes of the materials are altered, but their chemical composition remains the same.
