Question

In cold regions, in winter the pipes for water supply break.

Answer 1

1. In cold region, as temperature reaches below 4 °C, water instead of contracting, starts expanding due to its anomalous behaviour.
2. As temperature decreases from 4 °C to 0 °C, volume of water increases continuously.
3. At the same time, metal pipes carrying water undergo contraction.
4. As a result, pipes experience force applied by water and break.
