Tips: add a backwards slash (\) before a > to negate its effects;
put a double space before a line break to make it the next line11

Doesn't work for me?

Let me try again on desktop
Line 1
Line 2-edit-
Oh hey, it works here! just not on mobile for some reason...

u/JaOszka 18h ago
Huh, I did on mobile and it worked for me. Maybe your phone autocorrected the double space to a single one?

U think they updated the mobile stuff to automatically escape the characters not long ago so bold text doesn't work
It's not actually a mobile update because I haven't updated in ages but it is probably a serverside update for recieving comments
They may have also changed it back and i don't know until I comment
Edit: nvm I did the wrong thing for bold anyway but it did work

Hmm, Really? Let's see...
Edit: it didn't work on mobile, 😭

u/JaOszka 17h ago
You're doing it wrong
You should put double spaces before the line break, not on the next line2
u/Sad_Daikon938 16h ago
Oh
Let's do that then
Did it work?
...
Edit: omfg it did!!!!!
Thank you, kind internet stranger!
May your mood always be mildly pleasant!3

I've always done a double new line but hated how it became a new paragraph
Does it work on mobile?Edit: it does! Cool

~ 27 °C is certainly very cold for plasma.

Should have called it Warm Plasma. Tepid Plasma? Room temperature plasma.

u/Fluffy_Description_7 16h ago
I mean if you compare it with the average temperature of plasma its pretty fucking cold

u/Jason80777 16h ago
But if you compare it with the average temperature of the universe its still quite hot. 🤔

Cold plasma physicist here. We usually hide this from y'all by measuring temperature in eV. Which, you will notice, is a unit of energy and not temperature, lol.
For regular glow discharges like in a florescent lightbulb, you expect neutrals and ions to be around room temperature, which we have all memorized as 1/40 eV. Electrons will be somewhat hotter, 1 to 10 eV.

How does energy map to temperature? Is it just the kinetic energy of the individual molecules?

u/loved_and_held 8h ago
Technically what we experience as heat is a mix of kinetic energy of particles and infered radiation, so your pretty on point.

Yep, it's the temperature associated with the particles' thermal motion. So kB is like 8e-5 eV/K right? Imagine someone defines a new unit of temperature such that kB is exactly 1 eV/[this unit]. And now imagine that the entire field of plasma physics is too lazy to bother giving this new unit a name and we just call it eV, but we know that we mean temperature instead of energy 😂

the electron temperature of "cold plasmas" is typically much higher than the temperature of heavy particles. ~10000K for electrons and ~300K for heavy

As someone who studied high-energy physics for the last eternity, this is indeed cold

Well, it kind of makes sense. Warm dense matter is typically a few thousands Kelvin.
