Answer:
The bending of metallic wire is reversible change. Because the bending of metallic wire can be reversed in its original form again that's why it is considered as a reversible change.

As you know that in reversible change no new substance formed. It can be reversed. Yes it's true that for sometimes a matter change its original property but it can be reversed again in its own orginal form. I will explain you by giving an example of reversible change. A liquid change into solid form on freezing or cooling. water is a liquid and it is changed into solid form which it is freezed. But as it is left in open area then it is reversed and comes again in its original form.
Answer:✓T
Explanation:The average velocity of the molecules of the gas at a given temperature is
V=✓(8 RT/πM)
i.e V is directly proportional to ✓T
