Sublimation

This is super very cool example of nature’s forces not to be reckoned with. If you look closely at the photo you see water sublimation occurring, as a result of sun striking ice on power line pole. The sublimation is observed as fog rises from the power line poles. There is a thin shiny layer of ice on the dark-colored power line pole.

When the sun is at a higher angle in the sky, it travels through less atmosphere and has a greater energy transmission. With enough energy imparted to the ice (a solid state of matter), in sublimation the ice will skip the liquid state and transform directly to the gaseous state. Incredible and beautiful !

In our kitchen’s lab we can use this process (sublimation) to essentially freeze dry and remove water droplets from raw materials – hence dehydrating.
