Which statements about thermal expansion are correct?
Hints
- Expansion coefficients differ from material to material.
- One familiar substance behaves anomalously just above freezing.
Show the answer
- A. Solids expand when heated
- B. Bridges require expansion joints to accommodate thermal changes
- C. Water contracts when cooled from 4°C to 0°C (anomalous expansion)
Why
Most materials expand on heating; water is anomalous near 4°C. Each material has its own expansion coefficient.
