Chopping wood

Bending a paperclip

Answer 1

Here's the classification of each example as a physical or chemical change:

| Title | Physical Change | Chemical Change | |------------------------------------------------------|---------------------|---------------------| | Digesting food | | ✔ | | Evaporating water | ✔ | | | Cooking an egg | | ✔ | | Mixing baking soda and vinegar to produce a gas | | ✔ | | Chopping wood | ✔ | | | Bending a paperclip | ✔ | |

Explanation:

• Chemical Changes (Digesting food, Cooking an egg, Mixing baking soda and vinegar) produce new substances with different properties.
• Physical Changes (Evaporating water, Chopping wood, Bending a paperclip) do not produce new substances; the material's properties may change, but its composition does not.
