Exam Integrated-Physical-Sciences Topic 1 Question 64 Discussion

Actual exam question for WGU's Integrated-Physical-Sciences exam
Question #: 64
Topic #: 1
Which action demonstrates a physical change?

Suggested Answer: B Vote an answer

A physical change is a change in the state or properties of matter without any accompanying change in its chemical composition. Chopping wood is an example of a physical change because the wood is merely being broken into smaller pieces, and its chemical composition remains unchanged. In comparison:
* Baking cookies involves chemical reactions, changing the ingredients' composition.
* Iron rusting is a chemical change where iron reacts with oxygen to form iron oxide.
* Milk becoming sour is a chemical change due to the fermentation process.
