Calorimetric experiments in water and the second critical point: Looking for an experimentalist
M. Marqués. Abstract Book of the XXIII IUPAP International Conference on Statistical Physics, Genova, Italy, (9-13 July 2007)
Abstract
An experimental proposal to test the existence of a liquid-liquid critical point in water, based on high pressure calorimetric measurements is presented on this paper. Considering the existence of an intramolecular correlation in the water molecule 1 we show how the response of the specific heat at high pressure is different depending on the existence, or not, of the second critical point. If the liquid-liquid critical point hypothesis is true there must be a maximum in the specific heat at some temperature $T_*>T_H$ for any pressure $P>P_c$ (see Figure), being $T_H$ the homogeneous nucleation temperature and $P_c$ the pressure of the second critical point. This maximum does not appear for the singularity free scenario.
