Sugar burning triggers a reaction of sugar with oxygen in the air and causes the formation of water and carbon dioxide. This change is a chemical change that is irreversible.
Let me explain why….
Why is Burning Sugar A Chemical Change?
Burning any substance or material is a chemical change since burning is the quick combination of a substance with oxygen.
During this new substances are formed and the old ones are destroyed meaning chemical bonds were broken and made. That my friend is the definition of a chemical change.
In the case of sugar burning, complete combustion results in only water and carbon dioxide. But, in practice, the combustion is often incomplete yielding a black mass made up of mainly ketones, carbon, aldehydes, and carboxylic acids.
In any case, these are all “new” compounds that weren’t there initially, because bond breaking and bond making took place.
Why Is Heating Sugar A Physical Change While Burning Of Sugar A Chemical Change?
Heating sugar melts it from a solid to a liquid state and this results in a physical change. This change is reversible in nature and does not involve the formation of any new substances.
Burning of sugar, on the other hand, leads to the reaction of sugar with oxygen in the air and causes the formation of carbon dioxide plus water. The change is irreversible and is thus a chemical change.
Got it? I thought so too, haha.
Is Heating Sugar to Form Caramel Chemical Or Physical Change?
Heating sugar to form caramel is a physical change since the transformation can be reversed.

Is Sugar Burning In A Pot A Chemical Change?
Sugar burning in a pot or skillet reacts with oxygen to convert to carbon dioxide and water vapor. This change is a chemical change since there is a change in the chemical composition of sugar.
Why Is Burning Of Sugar A Chemical Change Class 6?
For Class 6, sugar burning is a chemical change since it is irreversible and it yields carbon dioxide and water.
Is Sugar Being Heated A Chemical Change?
Heating sugar in itself is a physical change but if you heat it high enough, it will induce a chemical change: caramelization.
