what is the reciprocity theorem? and does ideal gas law PV=nRT follows the theorem?
This question is way too wide.
Here is Reciprocity theorem: http://en.wikipedia.org/wiki/Reciprocity_theorem
And no, ideal gas law PV=nRT is derived by combing Charles' law , Boyle's law and Avogadro's law and has nothing to do with reciprocity !!
