DEMONSTRATION OF THE INVALIDITY OF THE MPEMBA EFFECT
Journal Title: International Journal of Applied Engineering Research and Development (IJAERD) - Year 2018, Vol 8, Issue 2
Abstract
Demonstration of the invalidity of mpemba effect with thermodynamic processes and its operating method are described. The mpemba effect is a process, in which hot water can freeze faster than cold water. This assertion is counter-intuitive. Indeed, the mpemba effect breaches fundamental thermodynamic laws. In fact, that there is no evidence meaningful of the validity of the mpemba effect [1]:the phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because this statement is ill-defined; although the mpemba effect is real, it is unclear whether the explanation is trivial or enlightening. However, with these definitions, this effect has never been clear. On the other hand, there are many the circumstances in which the effect is not observed. The main references to the effect go back at least to the writings of aristotle [2], but the author shows that this effect is mistaken and shows the available evidence for negation of the mpemba effect and carry out experiments by cooling water in carefully controlled conditions. A mathematical demonstration has been presented, that violates the physical principle, coming to a contradiction of thermodynamic laws. The demonstration would show therefore, the mpemba effect cannot occur, and it does not exist if the initial parameters are correctly equivalents. The required vast multidimensional array of experiments explains why the effect is not yet understood and demonstrated. Therefore, it is necessary to verify all the previous/historical relationships are the result of a bad experimental technique, since evidently it started from incorrect assumptions. It is important and necessary to stress that, in order to validate the thesis: all conditions must be the same at any time.
