Answer 2

Answer:

Now we start from the 1) burning of cooking - Burning of cooking is just a irreversible changes which can't be reverse back into their state as well as before

Now 2) ripening of fruit - It is just a irreversible change because when a fruit ripen after that we can't converge into a unripen food so.

Now 3) conversion of water into ice - It is a reversible change because when water is in state of liquid and it coverged into ice solid state known as ice then we can reverse it back into it's liquid state by heat it

Now 4) preparation of curd into milk - It is irreversible change because when the milk changes into curd the is new bacteria form known as lactobacillus so after this formation we can't convert into milk again so it is called irreversible change

Now 5) Folding of paper - It is just a reversible change because when we fold a paper than we can make also as well as before so it is a reversible change
