(This is also applies to ideal gas law related topics, like Boyle's law, Charles's law, Gay-Lussac's law, etc.)
On a recent question about how a bottle of air behaves when the temperature changes, a commenter said:
This isn't a chemistry question [$\ldots$] This is just physics.
While the commenter didn't explicitly say that the question was off-topic for not being about chemistry, and should not have been asked at this site on that basis, that was the implication I read into it.
While for me the ideal gas law and related laws were always covered as part of the chemistry curriculum, I realize that there may be regional variation and a difference in opinion on this topic, hence my question to make it official:
Are questions on the ideal gas law on-topic for this site, or should they be closed or moved to some other site?
