Explanation:

• "Chemical" is the second type of change (opposite to physical).
• "Appearance" aligns with physical change description (form/appearance change).
• "Cutting" is a common physical change example (like cutting paper).
• "Transforms" describes how a substance becomes new in chemical change.
• "Vinegar" reacts with baking soda (a known chemical change example).
• "Physical" is contrasted with chemical changes in the clue part.
• "Original" makes sense as inability to revert to original form indicates chemical change.
