The energy in the spring is potential energy, which, when released, will produce physical (kinetic) energy--motion. The reaction between the HCl and the metal involves a chemical reaction, which is not affected by the potential energy of the springs (at least in this case). There is a transfer of energy involved in this chemical reaction (as in all reactions), but it is chemical energy on the atomic level rather than physical energy at the physical or kinetic level. It's been a long time since Chemistry, but this is my take....

Brian Holden >> Brian; Yes there is/was "energy" stored within the spring but it was contained within the spring as 'potential' energy and not realeased as 'kinetic' energy. All the energy stored within the spring will be realeased as 'heat' during the dissolution of the springs. Possibly by 'snapping' or'pulling' the spring apart when the diameter of spring reaches a point where the stored energy is strong enough to do so. My take :-) Jim Bryant (FL)
