Of course! FA - FB has to have the same trace, whichever c you pick, or your constraint is only true under certain conditions. I think I was getting confused by the concept of cancelling variables within an arbitrary function, because it's obvious in hindsight. Thanks for the help.

I think I 'cancelled out' the coordinates of C without using the zeroth law. Substituting constants into the equation is standard mathematical practise. That gives me: FAC(A1, A2,···; c2,···) = FBC(B1, B2,···; c2,···) Then I defined two functions: then substituted those defined functions...

Homework Statement I really don't know if I'm in the right subforum... I've started reading this text on statistical mechanics from MIT, but I'm stuck on page 2. Here's the statement: Let the equilibrium state of systems A, B, and C be described by the coordinates {A1, A2,· · ·}, {B1, B2,·...

Wow! Although the question still remains, that was an absolutely fascinating web page! Thank you very much!

I have read in wikipedia and other places that white holes cannot exist as they violate the second law of thermodynamics. I s'pose my question is a simple one. How?

I've tried it. Couldn't see anything about the 6 carbon intermediate though.

I hadn't. Now I have though, I know that they have sequenced it, but still don't know about the intermediate, surely it would be easy to find... why is it so hard?

pH = 14 + log[OH] as it is a strong base, the concentration of OH- ions should be the same as the concentration of (Na_3)(PO_4). Can you work it out from there?

I have been learning about the calvin cycle, and have been told that people think that ribulose bisphosphate is first converted into a 6 carbon sugar as a very short life intermediate, and then is converted to phosphoglyceric acid. Why can't you just synthesise rubisco, work out its structure...

Don't worry, it was more a general interest. Thanks for the help.

Hmm... Another imposible problem. Should have thought about the cell membrane. That will slow things down a bit! I thought the laws were derived from ideal gas equations assuming that particles had no attraction between them, no energy loss, small particle size etc.. If they have attraction...

I thought that equation was just for Gases? The idea was ions in the body.

Oops, I still think of it as room temperature and pressure :blushing: . Yes. I mean standard temperature and pressure.

Does anybody know the average velocity of a particle in solution at rtp?

You need to find the vertical componant of the velocity, by using trigonometry. Then you use suvat to find the time when distance is zero again (i.e. when the athlete hits the ground). Now you know the time when he hits the ground, and using trigonometry, you can find the horizontal...
