WATER VIOLATES THE SECOND LAW OF THERMODYNAMICS
Consider the "somewhat mysterious" pressure emerging between and
PUSHING APART the plates of a constant-charge capacitor immersed in water: http://www.amazon.com/Introduction-E.../dp/0763738271 Introduction to Electromagnetic Theory: A Modern Perspective, Tai Chow, p. 267: "Calculations of the forces between charged conductors immersed in a liquid dielectric always show that the force is reduced by the factor K. There is a tendency to think of this as representing a reduction in the electrical forces between the charges on the conductors, as though Coulomb's law for the interaction of two charges should have the dielectric constant included in its denominator. This is incorrect, however. The strictly electric forces between charges on the conductors are not influenced by the presence of the dielectric medium. The medium is polarized, however, and the interaction of the electric field with the polarized medium results in an INCREASED FLUID PRESSURE ON THE CONDUCTORS that reduces the net forces acting on them." http://www.amazon.com/Classical-Elec.../dp/0486439240 Classical Electricity and Magnetism: Second Edition (Dover Books on Physics), Wolfgang K. H. Panofsky, Melba Phillips, p. 114: "This means that if a system maintained at constant charge is totally surrounded by a dielectric liquid all mechanical forces will drop in the ratio 1/ k. A factor 1/k is frequently included in the expression for Coulomb's law to indicate this decrease in force. The physical significance of this reduction of force, which is required by energy considerations, is often somewhat mysterious. It is difficult to see on the basis of a field theory why the interaction between two charges should be dependent upon the nature or condition of the intervening material, and therefore the inclusion of an extra factor 1/k in Coulomb's law lacks a physical explanation." p.115: "Therefore the decrease in force... cannot be explained by electrical forces alone." pp.115-116: "Thus the decrease in force that is experienced between two charges when they are immersed in a dielectric liquid can be understood only by considering the effect of the pressure of the liquid on the charges themselves. In accordance with the philosophy of the action-at-a- distance theory, no change in the purely electrical interaction between the charges takes place." Common sense forces one to conclude that, if the mysterious pressure pushes the plates apart, then it will constantly pump water through a small hole punched in one of the plates. But the constant flow through the hole can in principle be harnessed to do work and so the second law of thermodynamics is violated. Could common sense be misleading in this case?

WATER VIOLATES THE SECOND LAW OF THERMODYNAMICS
http://farside.ph.utexas.edu/teachin...es/node44.html
"However, in experiments in which a capacitor is submerged in a dielectric liquid the force per unit area exerted by one plate on another is observed to decrease... (...) This apparent paradox can be explained by taking into account the difference in liquid pressure in the field filled space between the plates and the field free region outside the capacitor." So the pressure difference will constantly pump water through a small hole punched in one of the plates, won't it? Pentcho Valev |
