  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.

    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:

    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.

  Enter vapor pressure:

  Image

  Basically water always evaporates if the air is completely dry, until the air contains a certain amount of water (measured in partial pressure, which is the part of the air pressure that is caused by water vapor). This partial pressure is temperature-dependent, so if you have 20°C (normal room temperature) you’re gonna have 23 mbar of water vapor partial pressure in the air. Source

  So water still evaporates at lower temperatures when the air is dry enough. It’s just that at 100°C (“boiling point of water”), that partial pressure of water vapor in the air increases to 1013 mbar which is equal to the total pressure of the air; In other words, at that temperature in equilibrium, the air is totally made up of water vapor and nothing else. If you increase the temperature above that, the water vapor partial pressure tries to still increase, which makes the total pressure go above normal air pressure, which causes a pressure gradient and causes the air to move with mechanical force, which you can use to make turbines spin.

    A more microoscopic explanation is due to Maxwell-Boltzmann distribution.

    First, you need to underestand temperature. The difference between cold and hot water is the average speed at which particles move, with hotter water’s particles moving faster.

    But this is just the average speed, it turns out that particle’s speed can be se en as a random variable, and they follow Maxwell-Boltzmann distribution:

    Maxwell-Boltzmann distribution

    So you have a small proportion of particles that move very fast, even in cold water. If some of those particles get (or collide with other particles near) to the “layer” of water that is on contact with the air, they will have enough energy to escape water’s superficial tension, thus going into the air and out of the water body. The higher the average speed of the particles, the faster this process will go. Finally, the rate at which this process happens also depends on the energy required to be able to leave the water body, which depends on factors like air pressure.

      yeah i’ve of course heard about it and i’m studying physics myself rn so i’ll get to it.

      I simply haven’t taken the course on quantum physics yet so i don’t want to make bold claims here. I have yet to derive the classical phenomena from quantum physics myself.

  Water doesn’t need to boil to dry out.

  Obviously it’s just losing wetness over time.

  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.

  • ulterno@programming.dev ⁨2⁩ ⁨weeks⁩ ago

    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.

  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!

    Sounds like the same thing that happens at 0°C with very pure water that stays liquid, but shake it and bam! It insta-freezes.

  Temperature is based on “average” kinetic energy so technically there are molecules with higher energy’s that are higher than the transition state and that’s why

  Anon didn’t pay attention in physics class.

  For fun I’m going to explain why. So air can hold some amount of water in it at any temperature. Water energy in form of heat is not evenly distributed so some molecules move faster than others, at the surface some move fast enough to escape the water and into the air. That’s called evaporation, boiling does however require 100°C.

  This also explains why humid weather affects evaporation (lower capacity to hold water in air) and at high humidity there’s an a similar chance of water being deposited to the body of water as water escaping which affects evaporation speed a lot.

  Honestly, I really like this quality of water, it would be super annoying to deal with otherwise.

  You claim water boils at 212⁰

  Yet this sponge soaks it right to at room temperature.

  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.

  Water is air soluable.

  It’s just like how salt will disappear in water without needing to get hot enough to melt.

  Though both of them still need the thermal energy to do the state change, but they just borrow it from their neighbours.

  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.
