Question

In USA a lack of snowfall allowed the ground to freeze to a depth of about 1meter causing buried pipes to freeze and burst why did a lack of snow lead to this situation.

Answer 1

Answer:

Explanation:Water pipes burst because the water inside them expands is it gets close to freezing, and this causes an increase in pressure inside the pipe. When the pressure gets too high for the pipe to contain, it ruptures.

We grew up with water all around us and so this expansion phenomenon seems natural, but interestingly, it is a chemical anomaly. Most liquids do not expand just before transition to solid. You should be thankful for this; it is one of the reasons that life exists.

When a liquid cools the molecules slow down (temperature really is just a measure of the average kinetic energy of the molecules). This slowing down allows the molecules to get closer together and increases the density of the liquid. This happens with water too, and when water is cooled down, it gets denser and denser, down to 3.98°C then, something interesting occurs; it starts to expand again.

You can see this effect on the graph below which shows how the density of pure water changes with temperature (at one atmosphere). You can see how density reaches a maximum at 3.98°C.

Answer 2

Explanation:

water pipes burst because the water inside them expands is it get close to freezing and this causes and increase in pressure inside the pipe when the pressure gets too high for the pipe to contain it ruptures.when water is pulled down it gets denser and denser down to 3.98 degree Celsius when something interesting occurs it start expanding so show the lack of snow lead to the situation
