In this paper, we investigate some consequences of the black hole stabilization of Schwarzschild in the presence of quintessence type of dark energy which leads the way to the black hole mass decreasing other than the Hawking radiation process. The results show that in the quintessence field, the black hole shows a second-order phase transition, implying the existence of a stable phase. However, this stabilization implies some paradoxical effects on the black hole, which gives us a new regard about black holes, precisely we obtain the negative absolute temperature and we propose a process permitting us to appreciate well the likely cause of this phenomenon. These results allow us to give a new definition of the surface gravity for the Schwarzschild black hole in the field of quintessence, which depends on the flux of dilatation produced by the quintessence type of dark energy. Afterward, we analyze the impact of dark energy on the power and the time of two black holes needed to coalesce. Keywords: Quintessence, black hole, second-order phase transition, negative absolute temperature, gravitational waves
