The bursting of water pipes during very cold weather, when the water in the pipes form ice could be attributed to
contraction of pipes when cooled
expansion of water on freezing
contraction of water on freezing
expansion of ice on melting
Explication
The bursting of water pipes in very cold weather occurs because water expands as it freezes. This expansion increases pressure inside the pipes, which can lead to bursting.
