@Benzene I know, right?

Benzene

It reminds me of the burning duck feet question a while ago

Do you know if that question was taken down? I was trying to find it a couple of days ago.

orthocresol

@Benzene It was deleted five months ago. (Thankfully.)

@Benzene @ orthocresol I just read the spider question in class, and laughed so hard. Half the lecture hall and the prof turned around and gave me a good state down

Zhe

So, what you're saying is if we want to get you in trouble, post silly questions so you'll laugh out loud in the middle of class?

getafix

Yup pretty much. I have very little self control

Also a short attention span

And congratulations on making it to the board

@ringo are you a UT student? I remember talking to an active member of the community who goes to UT last year.

Hi :-) Is anybody familiar with Andrews P-V curves for $CO_2$?

user228700

I'm having a little trouble understanding this:

There, that diagram is a lot better ^

@Benzene Yes, I am

@Kaumudi what are you having trouble with

Oh, never mind, I figured it out, thanks :-)

I have another quick question. Vapour is defined as the state of matter of a substance below its critical temperature. What does this really mean?

user228700

5:42 AM

Oh, and also, does anybody know why pressure remains constant for awhile there, on the graph I posted earlier, as we keep reducing it's volume?

@Martin-マーチン @orthocresol @Loong chemistry.stackexchange.com/questions/61954/…

Not sure how the flagging for moderator attention works but figure I'd call your collective attention to it just in case

Martin - マーチン

@ringo This is no case you'd flag. It's just a question, that will probably be heavy down voted and maybe even closed. From a technical standpoint I see nothing really wrong with it. After all, there is some serious science analysing faeces.

ringo

I suppose

I think I was just averse to the use of "shit" in the title

@orthocresol chemistry.stackexchange.com/a/61946/15410 will you really turn blue if I sprinkle $\ce{FeCl3}$ on you?

Q: Coloured Crystal Glass using gold nanoparticles

I came across this video which shows how a crystal chandelier is made. I recommend that anyone reading this post should watch it; it is quite fascinating. Anyway, at about the 2:15 mark, the video talks about how ruby red crystal is produced by adding 24-karat gold powder to the glass. However,...

everyday-chemistry

^Need help selecting appropriate tags for this post.

I tagged it everyday chemistry for now...

@Kaumudi the pressure remains constant because the condensed phase is appearing, you squeeze the gas molecules together, some of them go into the liquid phase, there's no change in pressure..once the phase transition is complete, the pressure shoots up because condensed phases are quite incompressible.

@getafix Ah, OK, thank you :-)

Can anybody tell what this means? chemistry.stackexchange.com/questions/61963/…

o.o

I'm fairly sure it's something to do with surface tension, but I just don't get the question..

Loong

@orthocresol "Why is milk boiling over?"?

orthocresol

@Loong And, I guess, "why doesn't water boil over?"?

Loong

or "why doesn't water boil over so much?", since the volume of boiling water (and the mentioned tea) also increases due to the steam bubbles.

orthocresol

Ah, fair enough..

Loong

In a boiling water reactor (BWR), this effect is called "swell".

It can make the measurement of water levels in the reactor a bit difficult.

@Martin-マーチン Hey, what tags should I use for my question about coloured crystal glasses? I put down materials, and everyday chem..appropriate?

dunno... if not ok, somebody is going to fix it

fair enough

How goes?

Oops?

@Mithoron wut?lol

Hey I always wondered..what is your field? in chem..

Mithoron

@getafix I'm kinda sleepy

oh okay..

Mithoron

Got up early :(

getafix

ah damn

are you student?

Mithoron

@getafix I was doing various things

what does your username mean? is that your actual name?

Mithoron

oh lol..you're giving me nothing. haha

Mithoron

@getafix You can ask Loong or MAR about the nick

getafix

and I can't stalk your profile bio, cause you don't have one

:p

Mithoron

Mithoron

@getafix Studying advanced procrastination methods :D

getafix

oh hey we have that in common

Mithoron

@getafix Yeah it's quite popular field of interest around here ;)

getafix

yeah. I wish there was procrastination stack exchange

Mithoron

Well, this chat is permanent and even has built in search so one should be careful here

Q: what is cost of one water drop making in chemical method?

i want to know how much cost done by making chemical method of water drop.just please tell the amount of one water molecule.please send the reply,i am waiting for your reply sir

water

what?

Mithoron

@Loong :D

getafix

lol i just VTC'ed that question

orthocresol

why HW?

let's not let HW become a catch-all again... think this should be unclear

getafix

I was thinking that..but there was a hw vtc on it

so I just followed suite..I thought one of you guys put it there

Mithoron

1:17 PM

It's rather unclear or broad but guy behaves like homework noob

orthocresol

First,take a tour of site and see questions so that you can understand how a question should be asked on site,show your efforts,Try to keep the question clear and simple.If you miss a single step of all those i have mentioned,your question will bee massively downvoted. — THE LONE WOLF. 56 secs ago
