Question

• The definition of physical/chemical change
• The start/end products in a physical/chemical change
• The start/end appearance in a physical/chemical change
• The particular evidence observed to indicate a physical/chemical change.l

Answer 1

Folding paper into an origami owl represents a physical change because it alters the paper's shape without changing its chemical composition; the start product is a flat piece of paper, and the end product is a folded owl shape. The appearance has transformed from a smooth sheet to a three-dimensional figure, but the material remains paper throughout. Evidence of this physical change is observed in the reconfiguring of the paper's form, with no release of gas, color change, or formation of a new substance, which are typically indicators of a chemical change.
