Welcome back stackers to this week's challenge, comment first and win away the 1k sats
**Situation: ** You have 2 identical solid spherical bodies (A and B) placed in room temperature (~25 degrees celsius) in a dark room. Both have been freshly taken out from the freezer and have been left out in the room for cooling down. After about 1 hour you come back to the room and with a torch put light on both the bodies.
You can see A, but you are unable to see B when you put light on it. You find that one body B weighs less A.
On the contrary, A conducts electricity with almost 0 resistance and even conducts it when the electric current is taken away but B does not.
Then you heat both the bodies to 1000 degrees celsius and find that B becomes burning red and brighter compared to A.
Here is a graph comparing A and B
black - A, orange - B
**Question: ** What can be the 2 bodies?
This is an open ended question. Good luck!
Ok, since 12h have passed without any answers, I raise this bounty to 2000 sats
Hint: What are the bodies expressing? I want what they are in general not what they are made up of
You mean in abstract terms like "B is an absorbing object" while "A is a reflecting object"?
I mean like if an animal can fly, has feather and lays eggs - it is a bird is enough for me, you don't need to specify whether it is a sparrow or a blue jay
i gave another hint here #1024379 they are not real bodies but are concepts
We got our winner again! @didiplaywell put in good effort ;p (#1024805 to #1024866)
Answer: A is a superconductor and B is a black body.
stay tuned for next week stackers!
Thank you Sr :)
Without limiting the options to a specific material, generally speaking, object B could be an amorphous arrangement of molecules (hence its light absorption, low conductivity and less weight than A), and A could be a crystalline arrangement of molecules (hence its reflectiveness , superconductivity under low temperatures, and higher immutability than B under high temperatures).
you are doing a case study of the compounds which is indeed true but I want what are the two bodies A and B (not the materials)
Sorry I'm lost there.. you already specified the geometry of the bodies (spherical), their consistency (solid), and want to know what the bodies are but their material is not the answer. What property is left? Or what you mean is what they could be as real life objects? That is, not "metal sphere" but "cannonball"?
you can say, A is a conductor (not the answer) and B is a [something] in general terms.
Got it, then A is a superconductor and B is a superinsulator, thats for sure.
1 correct answer and 1 wrong answer :)
I'm certain A is a superconductor, and B does behaves as a superinsulator, so what else could it be is beyond me. I'm at loss here. But really appreciate the sats, thank you :)
superinsulators do not allow heat to flow through them along with electricity, it will be dimmer than A when heated to 1000 degrees which is contrary to the question, B appears to be a perfect emitter of heat (this is one hell of a hint)
Metal and graphite
nope
close but you can say it without specifying the material, moreover they are realistic bodies
Solid spheres for sure. 🤣
This one is over my head. Can we use ChatGPT to figure it out?
lol
i would recommend no
Thank you for the answer. I now see it got solved. At concept level I was there, but thought that that's not the catch and that I had to literally identify the objects. Next time I'm typing all I think. Great bounty! I will be here for the next one. :)
Pass 🤣
lol
