Answer 1

Answer:

Bursting of a balloon is irreversible but yet is physical as the properties of the balloon for example it's texture remain the same. It only goes through a change in it's physical properties for example shape.

b) It is an undesirable change as many people and innocent lives are dyeing. Which is definitely undesirable.
