I’m no lavatorial expert, but I’d guess the thermal conductivity of lava is relatively low. The high temp and high mass will keep it warm for a while, but water has a pretty high conductivity and capacity on its own. The agitation is distributing the heat too, well beyond the regular convection rate.
Bruh. Someone else on this thread has already clarified to you the easy and what I was expecting question: what happens to the water and lava in the water bucket.
You already answered that question in this thread.
I’m a software engineer, not a physicist, but I’m not sure that makes sense for this. Heat does transfer much more quickly in oil than water, so it can cool something off more quickly, but oil can also get way hotter than water. That little bucket isn’t going to hold enough for a lot of thermal mass, so it’s pretty quickly going to get as hot as the lava (or as close as oil can get). Water turns to stream and boils off, so kind of caps the temp under normal conditions.
Plus if they’re doing sampling, I doubt they want the sample covered in oil.
What surprises me is no way to carry the bucket away afterward; You would have to put your hand over the bucket, in the steam. Gloved or not, it does not seem very safe.
If it really is just getting the lava down to boiling water temperature, or even a bit higher, that thin metal handle will dissipate that heat pretty quickly. A glove should be fine.
With enough time, it will definitely boil off. You can see as the lava is cooling it’s transferring the heat to the water. The water is then converting to a gas (steam).
I wonder how hot the metal bucket is though. Can probably get 4-5 pick axes worth of lava before it melts the bucket
Is that an OSHA approved hand over the face to keep from breathing the poisonous gas?
I’m kind of surprised it’s not hot enough to boil off all the water in that little bucket pretty quickly, bit obviously it isn’t.

I would guess.
I’m not thinking that “lavatorial” is the correct word.
That conjures “lavatory”, which is something different.
For the science, yeah, more than enough water to cool the lava.
That’s just my experience. If someone does the math, I’ll love them.
If you replace the lava* with shit, the phrase still makes sense and is accurate
Do what math? I honestly don’t know what you guy’s actually expect it to look like, so I don’t know where to start explaining.
Seriously? The lava in water math.
It’s high school stuff if you bother to look up the specific heat and make some reasonable guesses.
It’s masters degree in thermal fluids engineering math

No it’s not. Google specific heat of lava. Shit’s been done already.
And not just for academics. Even Randall Monroe. He’s smart, but he’s not an academic.

Mate, I model thermal processes for a living. The question is: What is the question? What to calculate? What expectations are there to (dis)proof?

I really have no idea but my guess was the heat.
Was gunna say, looks like he’s looting the lava more than doing a carefully controlled scientific procedure.
OSHA completely missed the large ripped hole in the suit by his thigh…
That was from the last guy who did this job and died under mysterious circumstances. Nothing to worry about.
Could also be oil instead of water. I know they use oil to cool off blacksmithing stuff.

It is water:

Though for steel forging, oil is used depending on how fast they need to cool it down between forging steps.

I don’t approve of steel forging, steel customers deserve to know when they aren’t getting the real thing.

Well, until the water boils off, it can’t be hotter than 100C.
