Thermodynamics S and H propagation of errors and T correction
« on: November 10, 2012, 04:28:49 PM »
Hi everyone! Hope you're all having a good weekend!

So I have two questions for a p. chem lab I did.  The first one is for the propagation of errors for S and H that were measured in the experiment for boiling water.  Now I'm not to sure what to do for that, they are giving us a pile of equations in the lab that I've never used before, instead of using those can I just do

H=H(T,P) and go from there, develop it, and then to the propagation of error for a function of multiplication? Same with S=S(H,T)?   I'm sorry if I'm being a bit confusing, I have a really hard time understanding physics.

Also, we need to make a stem correction on the temperature because our pressure was 740.1mmHg.  I was thinking P1/T1=P2/T2 but that seems was to easy compared to what we saw in class (but that was for correction of H, not T, therefore I'm not sure how to correct T)

Any help would be greatly appreciated, thanks loads!
