A hammer is used to pound a piece of sot metal into a new shape. If the metal is thermally insulated from its surroundings, will its temperature change due to the pounding?
Conservation of energy:
Energy can be transferred and be converted to different form. If the system is isolated, then there is no way for the energy to transfer from the surrounding. Also, we should note that the work done in a material can change the object's kinetic energy or internal energy.
Answer and Explanation:
Pounding a piece of sot metal is one example of doing work on the system. Some work is used in bending and deforming the material. In addition, it also increases the internal energy of the metal making its temperature increase a little bit. The system is insulated and thus the energy will not flow into the surrounding.
