How Antifreeze Works
I hate to report this but Peter Mander’s CarnotCycle blog has reached its last post for the calendar year. It’s a nice, practical one, though, explaining how antifreeze works. What’s important about antifreeze to us is that we can add something to water so that its freezing point is at some more convenient temperature. The logic of why it works is there in statistical mechanics, and the mathematics of it can be pretty simple. One of the things which awed me in high school chemistry class was learning how to use the formulas to describe how much different solutions would shift the freezing temperature around. It seemed all so very simple, and so practical too.
