WebA relationship between q and ΔH can be defined knowing whether q is endothermic or exothermic. An endothermic reaction is the one that absorbs heat and reveals that heat is consumed in the reaction from the … Weblowered. The heat removed from the beverage is not destroyed but instead is absorbed by the ice, changing the ice from a solid to a liquid. The second principle is that heat naturally flows from a higher temperature substance to a lower temperature substance; in other words, from hot to cold. Heat cannot flow from a cold substance to a hot ...
