AI Thread Summary
The discussion centers on the distinction between physical objects and the concept of "amount of substance," particularly in relation to elementary particles. It emphasizes that objects and amounts of substance are fundamentally different, using analogies to illustrate the confusion in the original question. Participants seek clarification on whether the inquiry pertains to the completeness of the particle list, the composition of the universe, or the relationship between mass and elementary particles. The conversation also touches on the mole as a unit of measurement, explaining that it quantifies a specific number of particles, such as photons, while noting the unique behavior of quarks, which cannot exist in isolation. Overall, the thread highlights the complexities of discussing particle physics and the need for precise language in scientific inquiries.

An object is an object, amount of substance is amount of substance, these are completely different things. Your question doesn't make sense.

You could as well ask what color is sweet, or whether sand is a chicken.
 
I don't know how call those things, some haven't mass, charge, spin and maybe still volume! In other words, all the particles (incluinding the photon), every what is possible quantify, are amount of substance?

We are having a lot of problems parsing your sentences in this question. Are you asking more like one of these?

-1- Are the particles listed on those pages all that there are. Could there be other particles?

-2- Is everything in the universe made up of those particles?

-3- Is the mass of an object made up of the masses of those elementary particles in the object?

...Or some other variation? Can you give a more detailed explanation of what you are trying to ask?
 
Mole is just an overgrown dozen - just like dozen holds 12 objects, mole holds 6.02×1023 objects. So technically yes, we can talk about mole of photons. Whether it is possible to have a mole (or several) of strange quarks is another question. Quarks are never found in isolation.

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
