Question

Bursting of a cracker is an undesirable reversible change.

• A. True
• B. False

Answer 1

The correct option is B False

• The bursting of crackers is a chemical change because it produces new products with different properties.
• It is also irreversible because once crackers are burnt, they cannot be converted back to their original form.
• Chemical change: A change in which the composition and chemical properties of the substance get changed is called a chemical change.
• During a chemical change, one or more new substances are formed.
• Irreversible change: The change which cannot be reversed even by changing conditions is said to be an irreversible change.

Hence, the given statement is false. I.e., the bursting of a cracker is an undesirable reversible change.
