# Query on Negative Temperature, Internal Interactions and Decrease of Entropy

@article{Chang2007QueryON, title={Query on Negative Temperature, Internal Interactions and Decrease of Entropy}, author={Yi-Fang Chang}, journal={arXiv: General Physics}, year={2007} }

After negative temperature is restated, we find that it will derive necessarily decrease of entropy. Negative temperature is based on the Kelvin scale and the condition dU>0 and dS 0. But, negative temperature is contradiction with usual meaning of temperature and with some basic concepts of physics and mathematics. It is a question in nonequilibrium thermodynamics. We proposed a possibility of decrease of entropy due to fluctuation magnified and internal interactions in some isolated systems…
