Vell, a compressed spring has potential energy stored in it. If this compressed spring is put into concentrated acid, (still compressed), the spring gets dissolved, now what happens to the potential energy of the spring???? is it releasd as heat or gets stord in aacid or both??? hw do v calculate the energy releasd on dissolving a compresd spring??

Well, when the spring gets dissolved, the elastic potential energy is passed on to the acid that the internal energy of the acid increases and hence the temperature. If the compressed spring gets completely dissolved, then the entire potential energy should be transferred on to the acid's internal energy. If not, the energy released may depend on the % of dissolution.

The change in internal energy will result an increase in Temperature
The solution provided explains all
