When we burst a cracker, is it correct to say that the chemical energy of crackers get used up or are destroyed as we are left with just ashes after bursting cracker?

Expert Answer
Its wrong to say that energy gets used up or destroyed. According to law of conservation of energy, energy can neither be created nor destroyed it just converts from one form to other.
On bursting a cracker the chemical energy of crackers transform into heat and light energy.
