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.
