Talk:Thermodynamics equations

Is PV=NRT a linear transformation? Or an integral function?
In T.W.,students uiversally accept concepts of PV=NRT being taught by teachers in class affording to juge a thermo-process's kind.

I truely think that it is rediculous. Because of they ingnore much more details about something like

$$(\frac{\partial{V}}{\partial{T}})_p(\frac{\partial{P}}{\partial{T}})_v$$.

(Note:one formula exists three viriables(functions),and parts of them play dilute roles: constants and functions)

Some students in my country(Taiwain) do not realize very much about PV=NRT as a linear transformation whether really do. If we observe a small region d(PV), it represents work done by a system. But we can not immediately concluse as

PdV+VdP=nRdT

Generally speaking,it is accepted only two viriable numbers in a function of thermodynamics. And more meaning of that is how we ensure dT whether belongs a group of molecules' performance of average kinetic energy or a infinite small temperature observed on a scale? --HydrogenSu 17:41, 19 December 2005 (UTC)
