Is peeling a potato physical change?

Peeling a potato is a physical change. Here's why:

* No new substance is formed: Peeling only removes the outer layer of the potato. The potato itself remains the same chemically.

* Change in appearance: The potato looks different, but its composition is unchanged.

* Reversible: You could potentially reattach the peel (although it wouldn't be practical).

In contrast, a chemical change would result in a new substance being formed, like when you cook a potato and it changes color and texture.
