Hello there, I was looking up explanations about intensive/extensive properties and I'm not too sure what is meant by " non-interacting subsystems" when it comes to extensive properties. I've tried googling the term but that came up with nothing. Could someone please tell me what is meant by "non-interacting subsystem" or direct me to a site which can.

Thanks heaps...

Where did you find the term "non-interacting subsystems"? You might try reading "non-interacting" and "subsystems" in the literal sense of the words.
 
I tried that, but it always comes up with things relating to particle physics, and the sites assume knowledge about the topic (which I don't have). Also the terminology used is very hard to follow.

I originally found the term on Wikipedia, but it pops up on other websites as well.
 
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...
