competition can really sharpen your skills I believe

I don't have much of a prob with ochem. Concepts are easy enough to deal with, some memorization, and some spacial orientation issues for some people. The pchem is what is getting me. It is multivariable calculus based and I have to admit I didn't enjoy multi-variable calculus either.

I have my dream med schools like Johns Hopkins but I have a much better shot here at the U of MN and it has great research department so I look forward to going here. Too bad about the hives, but then again a lot of requirements for getting in the military are waiverable.

taking organic right now. had to take p-chem or biochem to get into upperdivision and I can't take bio til next spring. So here I am in pchem.

Yeah, this is for physical chemistry. I took gen chem last semester and that was easy enough but for some reason p-chem isn't sinking in fast enough.

I'm a sophomore just starting college at the unversity of minnesota. I'm a sophomore because I've taken classes while I was in the army. The army also explains why I'm 25 and just starting college. I study engineering and work in kidney transplant research with plans to take the MNCAT this spring. So blike, maybe I'll see you in med school someday.

Just starting college. Why? Are my posts a little simple minded?

Items that are measured directly: Temp measured by thermometer Pressure by barometer Volume by ruler or water displacement... Enthalpy by ????? Enthalpy can be measured, it is how we have our Cp and Cv values (probably) but if someone wants a H or U or S value they won't use an instrument to do it they will measure other simpler things to measure and then calculate the others.

I was under the impression that dH is calculated. You measure the temp change. such as in dH=CpdT In the lab you don't directly measure the H, you measure the dT and calc the dH.

I was assuming that it meant to express a value a collection of thermodynamic values (such as H, enthalpy, as you mentioned or H or U) which would give you a "thermodynamic definition" vs. if you defined the same value with "measurables" such as Pressure, Volume, and temp. But I'm not sure about that and I can't seem to find a definition in my textbook or online.

In physical chemistry, when the thermodynamic definition of a value is discussed vs. its mathematical definition what difference are we talking about
