Question

In cold countries, water pipes sometimes burst, because

• A. Pipe contracts
• B. Water expands on freezing
• C. When water freezes, pressure increases
• D. When water freezes, it takes heat from pipes

Answer 1

The correct option is B Water expands on freezing

In anomalous expansion, water contracts on heating and expands on cooling in the range $0^{\circ }Cto{4}^{\circ }C$. Therefore water pipes sometimes burst, in cold countries.
