A) it will break
B) its temperature will reduce
C) its temperature will increase
D) there will be no change in its temperature
Correct Answer: C
Solution :
Due to tension, intermolecular distance between atoms is increased and therefore potential energy of the wire is increased and with the removal of force interatomic distance is reduced so the potential energy is also reduced. This change in potential energy appears as heat in the wire thereby increase in its temperature.
