So this is dictated, this must happen by the second law of thermodynamics. So over time, almost all of these red molecules, the majority of these molecules in our dialysis bag, will essentially move out of our protein mixture. So over time, the majority of the small molecules, the ions, for example, will pass through the semipermeal membrane and out of the bag. So energy will disperse because all these molecules carry energy. In this case, all the molecules were localized in the bag. So all the energy that the molecules carry was localized in the bag.
