MCQ
In cold countries, water pipes sometimes burst, because
  • A
    Pipe contracts
  • ✓
    Water expands on freezing
  • C
    When water freezes, pressure increases
  • D
    When water freezes, it takes heat from pipes
✓

Answer

Correct option: B.
Water expands on freezing
(b) In anomalous expansion, water contracts on heating and expands on cooling in the range $0^{\circ} \mathrm{C}$ to $4^{\circ}\mathrm{C}$. Therefore water pipes sometimes burst, in cold countries.
