MCQ
In cold countries, water pipes sometimes burst, because
- APipe contracts
- ✓Water expands on freezing
- CWhen water freezes, pressure increases
- DWhen water freezes, it takes heat from pipes
✓
Answer
Correct option: B.
Water expands on freezing
b
(b) In anomalous expansion, water contracts on heating and expands on cooling in the range $0°C$ to $4°C$.
(b) In anomalous expansion, water contracts on heating and expands on cooling in the range $0°C$ to $4°C$.
Therefore water pipes sometimes burst, in cold countries.
