The Periodic Table

8:42 AM

@gateprep I think you've got to assume an a rod (of arbitrary dimensions) and use your intuition :/

Poisson's ratio, denoted by the Greek letter 'nu', ν {\displaystyle \nu } , and named after Siméon Poisson, is the negative of the ratio of (signed) transverse strain to (signed) axial strain. For small values of these changes, ν {\displaystyle \nu } is the amount of transversal expansion divided by the amount of axial compression. == Origin == Poisson's ratio is a measure of the Poisson effect, the phenomenon in which a material tends to expand in directions perpendicular to the direction of compression....

According to the table there, your answer must be rubber :3

@ortho I'd really like to have a discussion about "something" with you. Could you ping me with dates/times you can spare (for a ~30min discussion). Thanks! O:)

(Yeah, I know you're fairly busy nowadays)

Question: Anyone here using the Compendium of Organic Synthetic Methods (or know anything about it)? @Loong @Mart @Zhe @ringo @DSVA @Not @Mith (Sorry for the Mass-pinging :(, I don't know any organic chemist I can ping ever since Jan disappeared)

There are 13 volumes in the series

I had a brief look at volumes 1-3 and they all seem to be from the 1970s. All, the tables of contents appear to be the same as well :/

I think volume 13 is from around 2005 or so...

I'd like to know if I should just get Vol.13 or the previous volumes as well O:)

@paracetamol Can u help me in chemical thermodynamics

paracetamol

@gateprep In a week's time, yes O:)

But what's up?

gateprep

Have u heard of callister?@paracetamol

paracetamol

A person?

Nope, never ._.

amazon.com/Materials-Science-Engineering-Introduction-8th/dp/…

gateprep

Basically he is the author of a book...I am just telling u the topics ...You will understand whether my topic is your cup of tea only after seeing that

@paracetamol

paracetamol

Material Sciences aren't my cup of tea XD

Sorry :/

gateprep

1:39 PM

I am just telling u the topics

paracetamol

@Mith Hullo! o/

Mithoron

\o

paracetamol

Tickles @Mith furiously till his hair falls off

@Mithoron Ah, hi! XD

Mithoron

0.o

Never heard of that book (afair)

paracetamol

Nothing, I thought you missed the "hullo", so I resorted to tickling...my bad O:)

this might be long@paracetamol

Introduction; types of systems; state functions and path functions; extensive and intensive properties;
reversible and irreversible processes.
1st law of thermodynamics; internal energy and enthalpy; heat capacities of gases, liquids and solids;
application of the 1st law to isothermal, adiabatic, constant pressure and constant volume processes with ideal
gas as system; thermochemistry; Kirchoff’s equation; adiabatic flame temperature; H-T diagrams.
Carnot cycle; entropy; different statements of the 2nd law of thermodynamics; statistical interpretation of

paracetamol

@Mithoron Thought so.. (I haven't either)

@gateprep Except for the last two, I've been introduced to the other stuff...

Physical Chemistry isn't really my thing though; If I'm answering anything, I'll need to refer my notes, which are back at home

Gaurang Tandon

"Please show the solution of formulae on how u reach to 35.5) with some English words so I can write the answer in my homework assignment and please make it small" a classic that never fails to amuse xD

paracetamol

And I'm away from home (technically on vacation) ._.

gateprep

No problem@paracetamol....I am happy if u can guide me with the rest.R u thorough with Kirchoff equation for enthalpy?

paracetamol

Which is why I said I might be of help in a week's time (when I get back)

@gateprep Depending on how you define "guide" I might :3

gateprep

1:50 PM

Ok then I will ping u after 21st?

paracetamol

I'd suggest elements of physical chemistry (Atkins), if you're willing to read up on it your self

Well, I get back by the 25-26th..

gateprep

@paracetamol R u an Indian..Just for curiousity..

paracetamol

Also the Chemical Engineering book by Cenegal is pretty good

gateprep

ok I will consult

paracetamol

in JEE/High School Chemistry Problems, yesterday, by paracetamol

Why is it that every Indian I've met on Chem.SE seems to be strongly inclined to assume that I, the paracetamol, am from anywhere but India ಠ_ಠ

@GaurangTandon "Solution of Formulae?" :3

gateprep

1:54 PM

:P:P ok then u might be a Keralite...

I mean a Keralite Indian

Gaurang Tandon

@paracetamol his engliss is week...

paracetamol

I noticed :3

gateprep

@GaurangTandon@paracetamol whose?

mine?

@Gate Honestly You might be better off posting questions on the main site (physical chem), since Ivan roams those lands...

gateprep

I dont even qualify for that..

The main site is too formal...

1:58 PM

But if you had to ask someone for clarification in chat, I'd go with this order: Philip = Mart = ortho = Zhe > Me

Gaurang Tandon

Philip is hardly around though @paracetamol

paracetamol

(Not sure if Loong'd be willing to... but he's epic with Org and Nuclear Chem)

gateprep

I hardly find them..

Btw whose English were u talking about?

paracetamol

pH13 - Yet another Philipp

6k 1 26 56

I meant him ^

;-)

Granted, he's usually only active on the g-block...

Gaurang Tandon

@gateprep some user who posted an average atomic mass question on the main site

@paracetamol ah, he's the "another" philip ;)

"Keralite Indian" isn't even a thing by the way ;-)

Just Keralite will do :3

gateprep

Then I predicted u correctly

:P

I am a Bong

paracetamol

I see... ._.

Or judging from the Topless-Putin-riding-a-Bear calendar I have on my door, I could very well be a Russian :3

Q: Is rearrangement possible in cyclic bromonium ion?

I wonder what the product of the above reaction is, that is, bromination of the given alkene in non polar solvent carbon tetrachloride (proceeds through cyclic bromonium ion intermediate). Once the cyclic bromonium ion is formed, can the ring expand as shown or is the usual product formed? Fi...

Q: Rate of catalytic hydrogenation of alkenes

What does the rate of catalytic hydrogenation of alkenes depend upon? What'd be the increasing order of rate towards catalytic hydrogenation of the following alkenes, A (2-methylpropene), B (cis-but-2-ene), and C (trans-but-2-ene)? I suppose this has something to do with sterics and orientatio...

Can anyone help this fellow?

Hello sir... I have doing my experiment over finding concentration of unkown samples of Congo red dye . But by mistake I lost my all absorbance data over known concentrations..so it's impossible for calculate unkown sample concentration.So please help me to come over this situation.
