ATP is an unstable molecule in unbuffered water, in which it hydrolyses to ADP and phosphate. This is because the strength of the bonds between the phosphate groups in ATP is less than the strength of the hydrogen bonds (hydration bonds), between its products (ADP + phosphate), and water. Thus, if ATP and ADP are in chemical equilibrium in water, almost all of the ATP will eventually be converted to ADP.

Definition - What does Attrition mean? Attrition is a type of erosion that occurs when bed load erodes. It is characterized by wearing of land as well as the removal of dune sediments, rocks and other particles by the action of tidal currents, wave currents, high winds and other factors. In attrition, rocks and other particles are carried downstream throughout river beds. This kind of movement causes these particles to be broken into tinier fragments. This phenomenon can also take place in glaciated regions, where attrition is typically caused by ice movement.
