Answer :

The changes that can be reversed are


(I) Making a dough


(II) Rolling the dough to make a chapatti


In both these steps, there is change only in the physical state or form of the dough, which can be reversed.


The changes that cannot be reversed are:


(iii) baking the chapatti


(iv) drying and grinding the chapatti to make powder


As these steps involve a change in the chemical properties of dough, they cannot be reversed.
