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 still lives with his mom and she mopped up the spill.
Water operates on Celsius so it only needed to be 100 degrees retard
Water doesn’t need to boil to dry out.
Obviously it’s just losing wetness over time.
“Water can only fly when its a gas!!!” Words from losers that have never looked at the sky.
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
Enter vapor pressure:
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:
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.
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.
Im a lifelong flat earth denier
The oceans aren’t carbonated therefore flat earth
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:
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.
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!
Aseprite?
Oh no they’re poisoning the water supply with nonfree software
fun fact: asesprite used to be libre!

are you aware of that louis rossman video? look up “why clippy profile picture”
microsoft was still evil, back in the 1900s.
clippit is a bad symbol
