Question

martina is camping and needs wood for a cooking fire as well as for shelter. she gathers a variety of logs and branches from the surrounding area. she chops and shapes some of the larger pieces of wood into uniform shapes to build her shelter. what kind of change is taking place as the wood is chopped? a. a change in matter b. a change in physical property c. a change in substance d. a change in chemical property

Explanation:

When wood is chopped, its shape and size change, but its chemical composition (the substance itself) remains the same. This is a physical change, which involves a change in physical properties (like shape, size) without altering the substance's identity. Option A is too vague, option C implies a chemical change (altering the substance), and option D is incorrect as chemical properties relate to how a substance reacts chemically, not just physical alterations.

Answer:

B. a change in physical property
