The law of conservation of energy
The spring itself is elastic, after being compressed, the spring will have the tendency to return to its initial state, and therefore has elastic potential energy, which can be seen as the energy stored in the spring as a whole system, so the question arises: if the spring is compressed into a strong acid, then after the spring dissolves, where does the energy of the spring go?
