Density Ice Temperature

Click For Summary

The non-linear relationship between ice density and temperature is attributed to the unique molecular structure of ice and its phase transitions. An inflection point at approximately -20°C suggests changes in the arrangement of water molecules as temperature decreases. This phenomenon can be explained by the effects of hydrogen bonding and the formation of different ice phases. Graphical representations of this relationship can help visualize these changes in density. Understanding these dynamics is crucial for applications in climate science and materials research.

Why is it that the ice density vs temperature plot is non linear, it appears there is a bit of an inflection at T=-20C, does anyone know why this is?

Thread 'Need to anneal 5052 aluminum'

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
