You lost me at azeotrope.

Yes. Id use that word to confuse and then seduce young women when teaching at the university.

(kidding)

Now... can I interest you in a lecture on how the length of hydrocarbon compounds can dramatically change the physical properties? Meaning, size does matter?

Oh sweetie (tis is kp putting the moves on) you have a nice set of azeotropes.:o

[kp2171]

She said they were the same amount. How can a white wine and red wine in the same size glasses not have the same volume?

I assume they started with the same volume. Without that assumption, this is just unanswerable.

but when you take out 5 mL from one and put it in the other... the original white now has just 95 mLs.

I know its hard to get.

I'm good at this stuff and my instinct answer was off.

if all the reasonable assumptions are right... equal starting volumes and equal transfers, the math is the bottom line. White wins for higherst % by a smidge.

if the assumptions are wrong... k... too many variables for my liking.

Okay... I'll take your word for it.:)

Fyi... there can be threesome (tertiary) azeotropic mixtures... just saying.

[kp2171]

Nope. Take the poster word for it.

I'm just the idiot with a keyboard thinking he knows the answer.

LOL! Sure, bring it on. :)

oops. crap. wrong.

what worked in my head is wrong on paper.

first... you must assume that both transfers are equal in volume... that exactly the same volume was moved in both cases.

then...

lets pretend we have 100 mL of each wine in two glasses.

you take out 5 mL of white to the red. thats 105 mLs of wine in the "red" glass, 100 mL red with 5 mL white. its 95.238% red.

then you take 5 mL of this mixture to the white.

you add to 95 mL white 4.762 red and 0.228 mL white... for a total of 100 mL wine, but the composition is different... its just 95.228% white...

the reason is you are adding in a mostly red aliquot to a lesser volume of white. the lesser volume of white is what got me mentally.

pooh.

shouldve done the math first.

Okay, either it is too late and my one glass of wine did me in (not unusual), or you have a slight math error.

I worked it out as follows:

You start with 100 ml of white and 100 ml of red.
5 ml of white is moved to the red, so you now have 95 ml of white, and 100 ml of red with 5 ml of white added.
If you take 5 mil of this mix, 4.762 ml (=100/105*5) will be red and .238 (=5/105*5) ml will be white. This gets added to the 95 ml of white.

The original white is now (95 ml+ .238 ml) 95.238 ml white and 4.762 ml red.
The red mixture is now (100 ml-4.762 ml) 95.238 ml red and (5 ml-.238ml) 4.762 ml white.

They are equal.

In looking at your numbers, when you add the 5 ml to the 95, the correct numbers should be 4.762 and .238. It looks like a math error – as 4.762+.228 does not equal the 5 ml you are transferring, or another way to look at it is 95+4.762+.228= 99.99, not 100.

Please tell me I haven't embarrassed myself. :o

I just want to know where my wine is! ;)

It's sitting in front of me. One glass is pretty much my limit, so help yourself. ;)

Nowr breeng on anotherrrr riddle. Hiccup. :)

If it takes ten men 3 hours to dig one hole, how many men does it take to dig half a hole in the same amount of time.

[Alty]

Silly girl, men don't dig holes, they make their wives do that. :p

Is the answer 5?

I could make so many funny comments, but I won't. See - I told you... one glass of wine and I'm a goner already.

Anyway, no, not 5.

1?

They hired another crew?

10?

Math bites the big one! ;)

Give up? It's really a dumb riddle.

I totally give up.

Give me answer! Give me! I am knot a blonde! ;)

You can't dig half a hole! It would just be a different sized hole



I know - dumb. Somehow it made me giggle... it's that one glass of wine. I'm such a cheap date. :p

::banging head on desk repeatedly::

Why didn't I see that?

Must be the wine you gave me.

Ya, that's right, I blame you! ;) :D
