Question

marina 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 and shaped, its physical form changes (e.g., size, shape). A physical property change involves altering the physical characteristics of a substance without changing its chemical composition. Chopping wood doesn't change its chemical makeup (it's still wood, just in smaller, shaped pieces). A change in chemical property (like burning wood where it reacts chemically) or a change in substance (a new chemical entity formed) doesn't occur here. A change in matter is too broad; we need to specify the type of change related to properties.

Answer:

B. a change in physical property
