    I had this question in a mid-term in physical chemistry 20 years ago. I can’t remember the details but it is driven by the entropy in the system. Along with the things other have said about changes tight above the surface of the puffle.

    The teacher was explaining about conducting and not conducting, and we had a battery with lamp thing to test on various objects. I of course had to test this on a pencil and discovered semi-conducting. That was a serious “not today” sigh from the teacher.

    Anon forgot that temperature in a substance is not uniform. This normally doesn’t matter, but if a part becomes hotter than the boiling point it will leave before it has a chance to go back to average temperature. So yes, the water “went to 212” before evaporating.

    this feels like a potentially sincere attempt to recruit people into an anti-science conspiracy movement - this doesn’t really feel different than the kind of reasoning you see with moon landing denialists or flat earthers.

      It’s actually not a bad question, just one people don’t really think about. Why does room temperature water sublimate?

      It’s because the temperature is an average, and some molecules at the surface have enough energy to break their polar bonds.

        I wanna say Bill Nye had a little contraption that explained this phenomenon. A cup with a piston on one end that vibrated. The top part of the cup had a ring in the center where little balls in the cup could fit. The piston represented the temperature (energy). Even at a lower temperature, some balls could randomly fly into the little hole and into the other partition. Turning the temperature up (increasing the speed and power of the piston) made more balls more frequently “evaporate.” I wish I could find that demonstration again.

      Eh I wouldn’t take it too seriously, I’m pretty sure it’s a play on the whole running joke of “saying something ridiculous, then end it with ‘You guys don’t seriously believe this right?!?’” type of thing. I’ve seen many of these greentexts that used that format recently.

      It’s kinda funny to me because it loosely reminds me of same logic as those old rage comic “troll physics” memes like these:
