I'm an expert in the field of thermodynamics and fluid dynamics, with a particular focus on how materials behave under varying temperatures and pressures. It's my pleasure to provide you with an explanation of why frozen pipes burst when they thaw.
When water freezes, it undergoes a phase change from a liquid to a solid state. This process is known as solidification or freezing. One of the key characteristics of water during this phase change is that it expands. The reason for this expansion is due to the unique molecular structure of water. In its liquid state, water molecules are in constant motion and are relatively close together. However, when water freezes, the molecules arrange themselves into a crystalline structure known as ice. This crystalline structure is less dense than liquid water, meaning that the same number of water molecules takes up more space when they are in the form of ice.
The expansion of water as it freezes is approximately 9%, which is a significant increase in volume. This expansion puts pressure on the walls of the pipes in which the water is contained. If the water is allowed to freeze completely within a pipe, it can exert a tremendous amount of pressure. This is because the ice blockage prevents any further movement of water, and as more water freezes, the pressure inside the pipe increases.
Now, the critical point comes when the ice begins to thaw. As temperatures rise, the ice at the edges of the blockage starts to melt, allowing some water to flow again. However, the ice blockage itself does not disappear instantly. This means that the water flow is restricted, and the pressure inside the pipe remains high. The thawing process can also cause the ice to shift, which can further increase the pressure on the pipe walls.
If the pressure exceeds the structural integrity of the pipe, the pipe will burst. This is often a catastrophic event, as it can lead to significant water damage and costly repairs. The bursting occurs because the pipe material cannot withstand the high pressure, and a weak point in the pipe gives way, allowing water to escape.
To prevent this, it's important to insulate pipes properly, especially in areas that are prone to freezing temperatures. Insulation helps to maintain the temperature of the water within the pipes, preventing it from freezing. Additionally, allowing a small trickle of water to flow through the pipes can also help to prevent freezing, as the movement of water can help to keep it from solidifying.
In summary, frozen pipes burst when they thaw due to the combination of the expansion of water as it freezes, the pressure this creates within the pipe, and the continued pressure as the ice begins to thaw but before the blockage is fully cleared. Proper insulation and maintenance can help to prevent this from happening.

Instead, it has to do with pressure inside the pipes. When water freezes, its molecules crystalize into an open hexagonal form, which takes up more space than when the molecules are in their liquid form -- that is, the water molecules expand as they freeze. As the ice expands, it pushes water toward the closed faucet.Feb 14, 2014
