Question

Accepted Answer

To solve these questions, we analyze each based on the definitions of physical/chemical properties and changes:

### Question 10
**Definition**: Physical properties are characteristics observable without changing the substance’s identity.
- The first column (top) for Q10 has "Physical Properties color yellow", matching the description.
# Answer: Physical Properties color yellow

### Question 11
**Definition**: Painting paper (e.g., applying color) doesn’t change the paper’s chemical identity (it’s still paper), so it’s a physical change.
- The third column (top) for Q11 has "Physical Change color black", fitting a physical change.
# Answer: Physical Change color black

### Question 12
**Definition**: Melting, evaporation, condensation, sublimation are phase changes (physical changes, no new substance).
- The second column (top) for Q12 has "Physical Changes color purple", but wait—phase changes are physical changes. Wait, recheck: the top row for Q12 (first column) is "Chemical Changes color yellow"—no, phase changes are physical. Wait, the middle column (top) for Q12: "Physical Properties color purple"—no. Wait, the third column (top) for Q12: "Physical Changes color blue"—yes, phase changes are physical changes.
# Answer: Physical Changes color blue

### Question 13
**Definition**: Water freezing (liquid → solid) is a physical change (no new substance, just state change).
- The top row for Q13: "Physical Change color black"—no. Middle: "Chemical Change color white"—no. Bottom: "Physical Property color blue"—no. Wait, re-express: Water freezing is a physical change. The bottom row (third column) for Q13: "Physical Change color blue"—no, wait the top row (second column) for Q13: "Physical Change color black"—no. Wait, the bottom row (first column) for Q13: "Physical Change color blue"—yes, physical change.
# Answer: Physical Change color blue

### Question 14
**Definition**: Burning leaves (combustion) produces new substances (ash, CO₂), so it’s a chemical change.
- The top row for Q14: "Chemical Property color red"—no. Middle: "Chemical Change color yellow"—yes, burning is a chemical change (new substance).
# Answer: Chemical Change color yellow

### Question 15
**Definition**: Physical properties describe a substance *without* changing it (e.g., texture, density, volume).
- The top row for Q15: "Physical Properties color purple"—yes, physical properties describe the substance.
# Answer: Physical Properties color purple

### Question 16
**Definition**: Texture, density, volume are physical properties (describe substance without altering it).
- The top row for Q16: "Physical Properties color yellow"—yes, physical properties include these.
# Answer: Physical Properties color yellow

### Question 17
**Definition**: A physical change doesn’t form a new substance (e.g., phase change, shape change). If a physical change results in no new substance (or the same substance), the "Sometimes number color blue" column? Wait, no—physical change → no new substance. The middle column (second) for Q17: "Yes color grey"—no. The bottom column (third) for Q17: "No color red"—yes, physical change → no new substance.
# Answer: No color red

### Question 18
**Definition**: Bending a hinge (e.g., metal bending) is a physical change (shape change, no new substance).
- The top row for Q18: "Physical Change color black"—yes, bending is a physical change.
# Answer: Physical Change color black

### Question 19
**Definition**: An apple rotting involves decay (new substances, chemical change).
- The top row for Q19: "Chemical Property color grey"—no. Middle: "Chemical Change color red"—yes, rotting is a chemical change (new substances).
# Answer: Chemical Change color red

### Question 20
**Definition**: Changing state (solid ↔ liquid ↔ gas) is a physical change (no new substance, just state).
- The top row for Q20: "Physical Property color grey"—no. Middle: "Physical Change color orange"—yes, state change is a physical change.
# Answer: Physical Change color orange

(Note: Some answers may need rechecking due to image clarity, but the above follows physical/chemical property/change definitions.)
