Thermodynamics of Substances with Negative Thermal Expansion Coefficient | | I. A. Stepanov
; | | Date: |
20 Oct 2000 | | Subject: | General Physics; Classical Physics | physics.gen-ph physics.class-ph | | Affiliation: | University of Latvia, Riga, Latvia | | Abstract: | The 1st law of thermodynamics for heat exchange is dQ=dU+PdV. According to K. Martinas etc., J. Non-Equil. Thermod. 23 (4), 351-375 (1988), for substances with negative thermal expansion coefficient, P in this law is negative. In the present paper it has been shown that P for such substances is positive but the sign before P must be minus not plus: dQ=dU-PdV. | | Source: | arXiv, physics/0010051 | | Services: | Forum | Review | PDF | Favorites | |
