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 will increase

Answer

D

Explanation

When tension is applied , the distance between the atoms of the wire increases, there by increasing the potential energy of the wire. When the tension is removed, the potential energy decreases. This energy is converted into heat energy. So the temperature of the wire increases.
