Anon finds a glitch

  It’s interesting because very pure water without asperites can be heated above 100c at standard pressure at sea level without boiling. But once impurities are added to it it starts boiling vigorously!

    What are asperites?

      Imperfections in the surface of the container the water is in. Sorry, I intended to write ‘water in a container without asperites’!

  Anon didn’t pay attention in physics class.

  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.

    Nah. I remember back in high-school there were some who “disproved” the 3rd law of motion by pushing a door closed and saying that they didn’t go backwards.
    I didn’t care to engage them in debate.

    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 end with that phrase 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:

      The oceans aren’t carbonated therefore flat earth

  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.

    How did that work?
    Doesn’t pencil lead material just work as a resistor? It’s mostly graphite and clay, and shouldn’t have the required structure to work as a semi-conductor.

      In my case it gave off a few sparks at the contacts what really makes it interesting for young me.

  Water doesn’t need to boil to dry out.

  Obviously it’s just losing wetness over time.

    Many hikers pack dehydrated water on long camping trips. Just add water to rehydrate it and drink!

  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.

  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. This is why the water evaporates much slower—only a small portion of the water at a given time can evaporate.
