The diagram shows a force-extension graph for a rubber band. Consider the following statements

$I.$ It will be easier to compress this rubber than expand it

$II.$ Rubber does not return to its original length after it is stretched

$III.$ The rubber band will get heated if it is stretched and released

Which of these can be deduced from the graph

$III$ only

$II$ and $III$

$I$ and $III$

$I$ only

Solution

(a) Area of hysterisis loop gives the energy loss in the process of stretching and unstretching of rubber band and this loss will appear in the form of heating.
