Question

what is the difference between reversible and nonreversible change and write the process of making the yarn from fiber?

Answer 1

Non- Reversible changes= Changes which cannot be reversed are called non- reversible changes. It is also called chemical changes. For example Burning of thread.
Reversible changes= Changes which can be reversed are called reversible changes. It is also called physical changes. For example melting of ice.
IN THIS PROCESS , FIBERS FROM A MASS OF COTTON WOOL ARE DRAWN OUT AND TWISTED THIS BRINGS THE FIBER TOGETHER TO FORM A YARN.
The process is called spinning.

Answer 2

1)These changes can be reversed.
2)These are mostly physical changes.
3)This can be done in both directions.
Irreversible change:-
1)This changes cannot be reversed.
2)these are mostly chemical changes.
3)these can be done in one direction only.
