Question

Why bursting a craker is a fast change ?

Answer 1

becuz it bursts very fast.......and it is a chemical change too becuz after bursting of crackersone cannot make it again (the burst crackers)as the chemical properties are changed. Hence bursting ofcrackers is a chemical change.



it is a fast change becuz it undergoes chemical change, that is the explosion of chemicals present in the crackers quickly( explosion is a chemical change)
