Physics Elasticity Question 53
Question: If the tension on a wire is removed at once, then
Options:
A) It will fracture
B) Its temperature will decrease
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 molecules is increased and
Therefore potential energy of the wire is increased and with the removal of force interatomic distance is increased and so is the potential energy. This change in potential energy appears as heat in the wire and thereby increases the temperature.
