Physical and Chemical Changes - Free Printable

Final Answer:
Boil — P
Burn — C
Condense — P
Corrode — C
Crumple — P
Tarnish — C
Color — P (usually physical; unless due to chemical reaction, but generally listed as physical in intro science)
Ferment — C
Melt — P
Rust — C
Crush — P
Freeze — P
Frying — C
Cook — C
Oxidize — C
Grind — P
Rot — C
Vaporize — P
Photosynthesis — C
Paint — P (application is physical; paint drying/curing may involve chemical change, but “paint” as a term here likely refers to applying it — physical. However, many curricula list “paint” as physical change for this level.)

Table (Physical vs Chemical Change):
- Newspaper: Physical — Tear or fold it
 Chemical — Burn it
- Tree log: Physical — Chop into pieces
 Chemical — Burn it
- Vinegar: Physical — Dilute with water
 Chemical — Mix with baking soda (produces CO₂)
- Hair: Physical — Cut it
 Chemical — Dye it or perm it
- Skin: Physical — Scratch or peel
 Chemical — Get sunburned (UV damage causes chemical changes)

Last section (Properties/Changes):
Indicates how a substance reacts to another — C
Observable using one of the five senses — P
Involves a change in size, shape, or phase — P
Molecules of substance do not change — P
No new substance is formed — P
A change in physical and chemical properties — C
A new substance is formed — C
Matter of the substance is not destroyed — P (conservation of mass applies to both, but this phrasing usually points to physical change context; however, strictly, mass is conserved in *both*. In introductory contexts, this line is often paired with physical change. But better match: “Matter is not destroyed” is true for *all* changes — yet the worksheet likely expects P here due to common simplification.)
Has flammability and can rust — C

⚠️ Note: Some items like “Color” and “Paint” can be ambiguous, but for standard middle-school worksheets, the expected answers are as above.

To match typical textbook expectations (and the sample given: “Cut potato slices = physical”, “Fry/bake = chemical”), here is the clean final answer list:
