Peeling an orange is a physical or chemical change
Peeling an orange is a physical change.
Peeling an orange is considered a physical change. A physical change is a transforma
tion in a substance that does not change its chemical makeup. When you peel an orange, you are simply removing the outer skin or rind, which is made up of mostly cellulose, pectin, and other plant materials. The chemical composition of the orange itself remains the same.

A physical change is a change in the physical properties of a substance without forming a new substance. When you peel an orange, the peel is removed, but the chemical composition of the orange remains the same. The peel of the orange is simply separated from the fruit, without any change in its chemical structure or composition.
To determine if a change is physical or chemical, you can ask yourself if the substance involved is undergoing a chemical reaction, forming new substances. If the answer is no, like in the case of peeling an orange, then it is most likely a physical change.
In contrast, a chemical change involves a rearrangement of atoms or molecules, resulting in the formation of entirely new substances with different properties. For example, if you were to squeeze an orange to extract its juice, the process would involve a chemical change as the juice undergoes reactions, breaking down the complex sugar molecules (like sucrose) into simpler molecules (like glucose and fructose).
In summary, peeling an orange is a physical change because it only alters its physical appearance without changing its chemical composition.
