Question
Explain, why are the taps left dripping in sub-zero temperature during winter?

Answer

Water freezes at sub-zero temperature and in doing so expands (anomalous behaviour of water).
So taps are left dripping in sub-zero temperature during winter so as to provide sufficient space for expansion of freezing water.
