Is burning an irreversible change that produces no new substances?
Burning is an irreversible change that produces new substances. When a substance burns, it undergoes a chemical reaction with oxygen to form new compounds like carbon dioxide, water vapor, and ash. This transformation is not easily reversible, as the original substances are no longer present in their original form.
Whether the change caused in tar by heating is reversible?
The change in tar caused by heating is not reversible. When tar is heated, it undergoes chemical reactions that result in the formation of new substances, making it irreversible.
Why is burning paper not a reversible change?
