# Why do water pipes burst when the water in them freezes?

###### Wiki User

Because the water expands!

Water when it freezes - - expands. Therefore water in pipes will split the pipes; water in a glass will break the glass; water in plastic jugs will disform the jugs.

Becuase when water freezes, it expands and burst the pipe from the inside.

Water freezes at 0 deg C. As the water freezes in the pipes, it expands and it is the force of expansion which causes the pipes to burst.

Because when water freezes it expands thus bursting the pipes.

Water pipes burst during severe winter because water freezes and expands

because the water inside the pipes freezes which causes ice to be created, which then expands and causes the pipe to burst

Yes, copper pipes can burst when the water inside them freeze. This is because, when the water freezes, it expands with a considerable amount of force, against the pipe, bursting it.

Because water, almost uniquely, expands when it freezes.

Ice forms in the pipes. When water freezes it expands a little bit! In water pipes it sometimes expands just enough to split the pipe.The reason why water pipes sometimes burst in winter is because water pipes are full of water and in the winter the air is very cold, sometimes in the UK even 2 or 3 degrees celcius. Because the air is so cold, and the air is surrounding the water pipesDuring the winter, the cold air is surrounding the pipes, which has water. The air turns the water inside the pipes to ice. When water freezes, it expandes. The frozen water expanded just enough to cause the pipe to burst.

When water freezes in (unlagged) pipes during very cold weather, the freezing water in the pipes expands. This can cause splitting in parts of the water pipe, or in forcing open the joints in the piping. When the weather warms, so the ice thaws and the water flows once more in the pipes, so revealing leaks as water pours out through the splits and weakened joints. This is why most burst pipes are only discovered once the ice has melted.

It is important to protect water pipes so they don't freeze because when water freezes, it swells. If water is trapped inside the pipes the pressure from it swelling will cause the pipes to burst.

some times when temperatures go really cold in winters it causes water to freeze and as the water in pipes starts to freeze, the expansion that takes place when water freezes causes pipes to break

In the winter, water pipes can sometimes burst. This is because the water expands as it freezes into ice, and this causes an increase in pressure inside the pipe. When the pressure gets too high for the pipe to contain, it breaks and bursts water.

Water is unique. It expands in volume when heated, and also expands in volume when frozen (hence, burst water pipes (unless insulated) when there is a thaw after freezing winter weather).

Because ice (solid water) has a higher volume than liquid water. As water freezes the molecules stick together with hydrogen bonds but with large gaps in between thus the volume increases and expands

if water freezes in pipes it will break the pipes, literally.

Water pipes should not of themselves crack at any temperature, however if pipes have water in them the water will freeze at temperatures below 0oC. If this happens then as the water freezes it will expand (ice is less dense than water) and as it expands it will either stretch metal pipes until they burst or crack ceramic pipes. For this reason external water pipes are buried at a depth to which the frost will not penetrate and internal water pipes are lagged to keep them warm.

A plumber is a tradesman (or woman) who mends burst water pipes.
