How does pressure change inside a cylinder of a gas (say, carbon dioxide) at a given temperature, and external pressure - if gaseous carbon dioxide is released from the cylinder at constant temperature?
How can we draw a graph of pressure as a function of time?
Would it matter if the constant...
It's not a homework question, it's something I've been wondering about. What gave you the right to assume it's a homework question? Is that how Stackexchange works for every question they don't intend to answer? — schrodinger_162 hours ago
the entire problem arises over the use of the word "homework" itself
the OP is right that it isn't from their textbook, but that's because conventionally "homework" is supposed to mean just that
i personally find the use of the word homework ambiguous, and confusing for infrequent visitors, that's why I don't use it at all in my own canned comment: "Hi %name%, welcome to Chem.SE! We require you to show your efforts on this problem. What formulae/steps did you try? Where did you get stuck? Please add this to your question. Thanks! "
@AvnishKabaj I suggest using this canned response instead. It avoids mentioning "homework", as the very mention of the word "homework" can lead to a debate with the OP as to what is homework and what is not, as happened with you
i personally feel we all should drop the usage of the word "homework" altogether, as its usage on our site differs radically from its intended definition in the dictionary and elsewhere on the internet
and ends up confusing OPs quite frequently
------------------- the way I see it is that that FAQ post was created for textbook questions _only_ (where the "homework" makes sense), but later it got applied to every second question that lacked effort (and wasn't textbook homework). So, instead of creating a new FAQ, somehow people thought it good to expand upon the original one instead and yet retain the word "homework" (-_-)
and confuse generations of OPs
@any-regular is my summary right? ---^
hmmm, seems I am right. Math.SE originated the first usage of "homework" - and quite correctly. Their "homework" literally means textbook problems that students need help with
two months later, Phy.SE somehow considered it appropriate to also merge "self-study problems, puzzles" along with it - ruining the definition of the word homework, and sowing seeds of confusion that would irritate OPs for close to a decade now!
and since our former leader ManishEarth was a Phy.SE veteran, it makes sense why our community also follows almost the same guidelines as were set in Phy.SE
adding in the definition for completeness: "homework - schoolwork that a pupil is required to do at home" (oxford). It is even obvious to a layman that our definition of "homework" is completely inaccurate
imho, we should have a separate close reason for "low effort questions", or drop the word "homework" altogether
