Physics Elasticity Question 53

Question: If the tension on a wire is removed at once, then

Options:

A) It will break

B) Its temperature will reduce

C) There will be no change in its temperature

D) Its temperature increases

Show Answer

Answer:

Correct Answer: D

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.
