which describes a feature of the physical changes of all substances? \n can dissolve in water \n can conduct heat and electricity \n rearranges atoms to form new substances \n does not change the identity of a substance

Answer

Brief Explanations:

  • "can dissolve in water": Not all substances dissolve in water (e.g., oil), so this is incorrect.
  • "can conduct heat and electricity": Many substances (e.g., wood, plastic) don't conduct heat/electricity, so this is incorrect.
  • "rearranges atoms to form new substances": This describes chemical changes, not physical changes.
  • "does not change the identity of a substance": Physical changes (like melting, freezing) alter appearance/state but not the substance's identity. This is the key feature of physical changes.

Answer:

D. does not change the identity of a substance (assuming the options are labeled A - D as: A. can dissolve in water, B. can conduct heat and electricity, C. rearranges atoms to form new substances, D. does not change the identity of a substance)
