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?
