5! Err... 6!

Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many other states are known such as Bose–Einstein condensates and neutron-degenerate matter but these only occur in extreme situations such as ultra cold or ultra dense matter.

Yup!

Really we should talk about quasi particles too. Not exactly a state of matter but stuff like polaritons blur a few lines.

My brain is already hurting from all the things I thought were truths when I was younger just to find out that they purposely teach us wrong because to teach us correctly is too hard?!?

[-] naevaTheRat@lemmy.dbzer0.com 2 points 8 months ago

no, because it's everything is ludicrously complicated and the nuance often doesn't apply in the majority of cases or understanding it is contingent on knowledge that is much easier internalise if you operate under a simplistic assumption first.

Truth is for maths and logic, the rest is conjecture and models.

Like, water alone has like, five different phases IIRC.

Or was that helium?

[-] naevaTheRat@lemmy.dbzer0.com 4 points 8 months ago

you might by confusing "solid phases" for states of matter.

If we draw a phase diagram you'll see shit like ice, ice 2: the cooler ice, ice 9: radical edition or whatever but they're all solid phases. The they just have different structures.

Sort of like lamp black and graphite are both forms of carbon but not really because that's got to do with distinct bonding. A better example, if you know your steels, is martensite vs autensite.

[-] gandalf_der_12te@feddit.de 1 points 8 months ago

Yeah, that could be.

Still, what about glass or thermoplasts, that have a fluid transition between solid and liquid?

[-] naevaTheRat@lemmy.dbzer0.com 1 points 8 months ago

I dunno sorry, I never studied glasses. I'm gonna guess that it's probably not a true distinct phase and more likely a mix between various configurations, like a solid solution or sometimes. I'm just talking out my arse but.

It doesn't really matter, high level stuff like states of matter are pretty crude approximations anyway. Like yeah yeah you get enthalpy changes but that happens at all phase transitions so it's not exactly that special.
