Answer :

Several products are released during the hydrolysis of ATP. The products released are adenosine diphosphate or ADP, an inorganic phosphate and orthophosphate.  These are the products initially released during the hydrolysis of ATP. The other things that are released during this reaction or further hydrolysis of ATP are adenosine monophosphate, energy, another orthophosphate and water.  Actually energy is needed to hold the third phosphate with ADP. So when hydrolysis is done and the third phosphate is released, energy also gets released.
