Where does the potential energy go if a clamped spring is dissolved in acid?

Click For Summary
SUMMARY

The potential energy stored in a compressed spring, described by the equation P.E = (1/2)*k*a^2, is transformed during the dissolution of the spring in acid. As the spring dissolves, the potential energy converts into kinetic energy associated with the molecular motion of the resulting ions and hydrogen gas produced from the reaction. The dissolution process involves the formation of a salt and gaseous hydrogen, indicating that the energy is not lost but rather redistributed in the system.

Homework Statement


When a spring is compressed, potential energy is stored in it. If the spring is dissolved into acid; where does the potential energy go.

Homework Equations



P.E = (1/2)*k*a^2

The Attempt at a Solution


I tried but got no idea about it.
 
Physics news on Phys.org
The potential energy of an elastically deformed body is the extra energy due to inter atomic interactions when the ions are moved from their equilibrium positions in the crystal lattice.

When a metal reacts with an acid, we get a salt and gaseous hydrogen in molecular form. The salt is usually hydrated and totally ionized in the solution. Therefore, the end effect of this reaction is that ions of the solid have moved in the solution and hydrogen ions have received some electrons and bonded in molecules. I would guess the potential energy has converted into extra kinetic energy of the molecular motion.
