More Than Pipes Freeze

The big fear we always have around cold weather and buildings is pipes freezing. If a pipe bursts, there’s going to be water damage and that can lead to millions of dollars in property and equipment issues. Imagine a pipe flooding a computer room or dousing a multimillion dollar MRI machine? It turns out however, other things can freeze too. Expand and Contract When materials are heated and cooled, they will change in size. This is from changes in their atomic structure as we put more and more energy into something. In the case of winter, it’s more of a contraction as we suck the energy out of things. These effects can be observed in a couple of places. On the extreme end of the spectrum, you have the SR-71 Black Bird, which gets longer in-flight due to heating from atmospheric friction. On the more common end of the spectrum, poor ice water in a glass bowl that’s just had boiling water in it. The bowl usually cracks, because the ice causes parts of it to cool down rapidly and contract, but the rest of the bowl is still hot. Glass has a rigid, crystaline structure and the force of contraction overpowers the rigid molecular bonds. It causes it to crack or even shatter (so don’t try this at home). These effects occur on essentially everything, with varying degrees of destruction involved. No matter what, nature is always going to […]
