H-bond relaxation resolving Mpemba paradox (姆潘巴佯谬可解）

热度 1 孙长庆 2013-10-23 16:54

Heat-stiffened H-O bond resolving Mpemba paradox Mpemba effect-01.docx https://medium.com/editors-picks/d8a2f611e853 We demonstrate that the Mpembaparadox arises intrinsically from the release of energy initially stored in thecovalent H-O part of the hot O:H-O hydrogen bond. Gen ...
