Worked Solution & Example Answer:A student is studying examples of physical and chemical changes - OCR Gateway - GCSE Physics - Question 8 - 2022 - Paper 1
Step 1
Which row in the table shows a correct example of a chemical change and a physical change?
Answer
To identify the correct example, we need to analyze each option:
- Option A: Boiling water (Physical change) & Frying an egg (Chemical change). Both processes do not match as one is chemical and the other is physical.
- Option B: Boiling water (Physical change) & Melting ice (Physical change). This option shows two physical changes.
- Option C: Burning wood (Chemical change) & Frying an egg (Chemical change). Both are chemical changes.
- Option D: Burning wood (Chemical change) & Melting ice (Physical change). This option presents a clear distinction between a chemical change (burning wood) and a physical change (melting ice).
Thus, the correct answer is D.
