10-1.Thermometry, Thermal Expansion and Calorimetry
easy
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
Solution
(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.
