Question

Grinding black pepper is reversible change or irreversible change

Answer 1

Speaking in terms of chemistry, a change can be explained on physical grounds. Changes are very random or uncertain phenomena. Changes can be for the good or worse, depending on your view. You must be noticing different objects changing around you on a daily basis.

As we mentioned above, melting of ice, cooking of food are all changes that happen around us. In some cases, we find that the original substance can be recovered back, while in some other changes, you can never go back to obtaining the original substance.

Answer 2
