Folding paper is what type of change?

Answer and explanation

Correct answer: Physical change

The governing concept is that a physical change alters the appearance, shape, or state of a substance without producing a new substance. When paper is folded, its shape and perhaps its creases change, but the paper remains chemically the same material with the same composition. It can generally be unfolded, although a crease may remain. No new substance, gas, or reaction product is formed. Therefore option A is correct. Chemical change would involve a new composition, such as burning paper to form ash and gases. Condensation is gas-to-liquid change, and sublimation is direct solid-to-gas change; neither describes folding.
