Question 1 of 8
A physical change is a change to a sample of matter where some properties change, but the of the matter does not change.
Question 2 of 8
A reversible physical change is one that can be changed back to its form.
Question 3 of 8
All physical changes that involve a change of of matter are reversible.
Question 4 of 8
When wood is ground into sawdust, the change is because the sawdust cannot be turned back into the same piece of wood.
Question 5 of 8
A chemical change occurs whenever matter changes into an entirely different substance with different chemical properties. It is also called a chemical .
Question 6 of 8
Signs of a chemical change include the release of , a change of color, the production of an odor, and the release of heat or light.

Quick Read: What Counts as a Change?

Physical ChangeChemical Change

A physical change alters form or appearance but not identity (no new substances). Mass is conserved. Examples: phase changes, dissolving, cutting. A chemical change creates one or more new substances with new properties. Evidence: gas production, precipitate, energy change, color change, odor, or irreversibility. Mass is still conserved in closed systems.

Physical: Solid → Liquid
