Depending on the type of sugar (D-fructose, D-glucose or D-sucrose), heating sugar in an inert atmosphere results in melting. Each type displays a unique melting behavior.

When sugar is heated in an inert atmosphere, such as in the absence of oxygen, it undergoes a process called thermal decomposition. This leads to the breakdown of sugar into smaller molecules such as water and carbon. The reaction produces a dark brown/black substance known as caramel.

Does the sugar possess the same property before and after heating?
No. Sugar is a carbohydrate. After heating (or burning or charring) it is oxidized to carbon dioxide and water and the reaction is irreversible.
Would the sugar change take place without heating?
Heating sugar it is thermally degraded. But sugar can be modified also by other chemical reactions.
What chemical is used to test for reducing sugar?
Benedict's solution is used to test for reducing sugar.
How to filter sugar from water?
heating process
How do you dissolve more sugar cube in a glass of saturated sugar solution?
By heating the saturated sugar solution, and then adding more sugar.

Why does sugar turn to a brown liquid on heating?
On heating sugar suffer a reaction of thermal dissociation; some new compounds are formed an also carbon. The dissociation depends on the temperature and the time of heating.
What does heat do to sugar?
The effect which heat has on Sugar depends on how high the temperature is, and the duration of exposure, and whether an oxidizing gas [air for example] or an inert gas [or no atmosphere] is present: * At low heat, generally nothing happens. * At a somewhat higher heat, the Sugar can melt. * At more heat the Sugar can be scorched [called "caramalizing"]. * At greater heat, IF an oxidizing atmosphere is present, the the Sugar can ignite and burn. * If the sugar is heated to a high temperature in an inert atmosphere [as in an evacuated retort] then the sugar can be broken down into a combustible gas, but will not burn due the absense of any oxidizer. This process is called "Pyrolysis."
Is heating sugar to make charcoal a chemical or physical change?
It is a chemical reaction and is undo able
Is heating sugar to make charcoal chemical or physical change?
It is a chemical reaction and is undo able
What is the chemical change when heating a spoonful of sugar?
If the sugar is heated to a sufficient temperature, it will decompose and produce CO2 (carbon dioxide) and H2O (water). This would be considered a combustion reaction.
What is the reaction for when sugar breaks down to carbon and water when heated?
you are trying to make jam, but you messed up the directions. you boiled the sugar mixture for an hour and the temp got up to 400 degrees. it doesn't burn, but it has turned into something, what is it?

What compound was decomposed sugar or salt?
Sugar is easily decomposed by heating.
