• B. Mass is converted into energy during a physical change.
• C. Energy is always absorbed during a physical change.
• D. No new substances are formed during a physical change.

Answer: (D)

Verified step by step guidance

1. Understand that a physical change involves changes in the state or appearance of matter without altering its chemical composition.
2. Recall the Law of Conservation of Mass, which states that mass cannot be created or destroyed in a chemical or physical process.
3. Recognize that during a physical change, the atoms or molecules remain the same and are not rearranged to form new substances.
4. Note that since no new substances are formed, the total amount of matter before and after the change remains constant.
5. Conclude that the property explaining matter conservation in physical changes is that no new substances are formed, ensuring the mass stays the same.
