LIQUID EXPANSION RATIOS
« on: August 01, 2005, 01:45:33 AM »
Hi, i'm not an engineer, infact i'm a 16yr old student and i am conducting an investigation, but i couldnt do it alone so i need some help from the experts (you).

here is what i'm looking for. I need a list of as many liquid elements and compounds and their expansion ratios or gas factors AND boiling tempuratures (Preferably below 50 celcius). if that is too great an ask could you please tell me which liquid compound has the greatest expansion ratio when becomeing a gas and how expensive it would be to manufacture. ???

dont expect us to hand you all the info u need without u doing work. be more specific instead of asking for everything at one go.

That type of information is useful in gas chromatography inlet theory calculations.  It would be hard to find a chemical with a greater expansion ratio than water.  The basis is due to the liquid having a reasonably high density (more mass per unit volume) and low molar mass (using the ideal gas law, more # of molecules when vaporized).  Those two parameters (density, molar mass) are the most important factors in determining expansion ratios.

Dude, why dont you just get a copy of her paper, do it and put samk00's name on it?? lol

 samk00,
Try getting a copy of a book called
"SI Chemical Data,G.Aylward & T.Findlay,5th ed. 2002"
It will have every possible peice of info your looking for.

Cheers,
