Question

when the change in part 3 occurs, does the sample have different chemical properties? physical properties? check all that apply.
yes, different chemical properties
yes, different physical properties
none of the above

Explanation:

A chemical change results in a new substance with different chemical properties. A physical change only affects physical properties like shape, state, etc., without changing the chemical composition.

Answer:

If it's a chemical change, yes, different chemical properties. If it's a physical change, yes, different physical properties. So both "Yes, different physical properties" and "Yes, different chemical properties" could apply depending on the nature of the change in Part 3.
