a spring which has been compressed by tying its ends together is allowed to dissolve in acid.what happens to the potential energy of the spring?
Asked by | 17 Nov, 2012, 06:37: PM
answered-by-expert Expert Answer
In principle, the heat released when a compressed (or expanded) spring is dissolved is greater than the same spring dissolved in acid when it is in equilibrium. However, the energy of compression or stretching is small compared to the heat of reaction of the spring with the acid, so it is barely noticeable.
