Paheli mixed flou

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.
