Thank you! Very well explained. Related to this, way back in earth science class, I vaguely recall a phenomenon of something changing from solid to gas so rapidly it did not become liquid in between--I've forgotten the term that describes this...??
Sublimation is the act of changing from a solid directly to a gas - Carbon Dioxide changes from solid to gas at room temperature and pressure. Iodine crystals sublime on gentle heating
Ah, yes--thank you! Something like that nagging at the back of your brain can drive you nuts! ;-)
BTW--your link to your other article brings up 410 error msg: page does not exist..
