Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Why cooking food an irreversible change?
The definition of a chemical change is when one or more new substances have been made. Also chemical change cannot be reversed by simple physical means e.g. if the change was brought about by heating then cooling the product won't get you the original substances. So boiling water is not a chemical change (as you can re-condense the steam) whereas boiling an egg IS as the protein has been permanently changed (denatured).
