Is electrical conductivity considered to be an intensive variable? Please explain briefly why or why not if you decide to say yes or no! Thanks! Carey

Please excuse my ignorance, but what's the definition of intensive in this context? Just asking, Ric Peregrino ric@spd.hp.com

In article <92104.123138CCB104@psuvm.psu.edu> CCB104@psuvm.psu.edu asks: >Is electrical conductivity considered to be an intensive variable? Please >explain briefly why or why not if you decide to say yes or no! Thanks! >Carey I will assume this question was asked in the context of classical thermodynamics. In such a context "intensive" quantities pertain to the substance, but not to the extent, or size, of the system. Electrical conductivity is certainly in that category *classically*, but in reality conductivity is dependent upon nonlocal influences, and for systems with sufficiently small dimensions electrical conduc- tivity could certainly fail to satisfy the condition that it does not depend upon the size of the system. This in no way relegates conductivity to the "extensive" category in such cases. Leigh Palmer
