Question

5. Suppose it rained heavily in your area today. To go to school, you remove your shoes and hold
them in your hands and fold your dress. Are these changes reversible?
6. Doctors apply a thick coat of plaster of Paris (POP) over the bandage on a fractured bone.
POP becomes hard on drying and keeps the fractured bone immobilised. Is it a reversible
change? ​

Answer 1

Answer:

it is reversible because you can put your shoes

6. No, the change in plaster of Paris cannot be reversed. When water is added to POP, it undergoes a chemical change.
