Picture the following situation
Two flasks of acid, two springs, one clip. One of the springs is compressed and then held compressed by use of the clip. The second spring is left "free". Now both springs are dropped into the flasks of acid. The acid reacts with the metal of the spring, but not the clip, and dissolves the springs, creating a salt and hydrogen.
My question is this : what has happened to the potential energy that was in the compressed spring once the spring has dissolved ? Has it manifested itself as heat ? If not, then what ?
