If the tension on a wire is removed at once, then
A
It will break
B
Its temperature will reduce
C
There will be no change in its temperature
D
Its temperature increases
Answer
Its temperature increases
Explanation
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 and so is the potential energy. This change in potential energy appears as heat in the wire and thereby increases the temperature.
