Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?

Answer 1

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.

Answer 2

it is chemical reaction but not a reversible change, unless you rewind it

Answer 3

it is a chemical reaction because if you cut up the potatoes you cant stick it back together and you also cant un fry it.

Answer 4

Chemical reaction
