Is letting a cut apple sit out and turn brown a physical change or a chemical change?
- A Physical change
- B Chemical change
That's Correct!
It's Wrong!
When a cut apple turns brown, it undergoes a chemical change. This happens because the oxygen in the air reacts with enzymes in the apple, causing the production of melanin, a brown pigment. The process involves a chemical reaction that alters the chemical composition of the apple’s surface, indicating a chemical change.
