Burning or oxidization is always a chemical change. The process takes in Oxygen and Sugar and outputs different compounds including water, carbon dioxide, carbon monoxide, and other carbon residue.
Because scorching something cannot be reversed, and a chemical change is a change that cannot be reversed. If you were just putting sugar into water, you could get the sugar back to its original state by evaporating the water, and the sugar would stay at the bottom of the glass. That would be a physical change because you can reverse the change.
If you scorch sugar, you cannot make it un-scorched. It cannot be reversed. It is a chemical change.
melting sugar isn't a chemical change, its a physical change.it only becomes a chemical change if it is burnt because the energy from the fire brakes down the chemical bonds
If the temperature is below the decomposition temperature, then melting a physical change not chemical as the liquid sugar (or molten sugar) can be solidified again.
Melting a sugar cube is a physical change because the substance is still sugar. Burning a sugar cube would be a chemical change because it activates a chemical reaction.
It is a chemical change because its still sugar its not being changed or transformed
Melting is a physical change; but when the temperature is sufficiently high sugar is thermally decomposed - and this is a chemical change.
Yes.Yes.Yes.Yes.
No.
Yes ,it is physical change because anything that forms a new substance is called physical change Yes, BUT, a MELTING ice cube would be a chemical change.
That would depend on how you define "change" and "sugar cube". If moving a sugar cube changes it, since you could move any sugar cube to an uncountable number of other locations, such a sugar cube could change in an infinite number of ways. If you define "sugar cube" as a six sided solid of glucose, you could substitute any one or more of several billion atoms for its isotope, and change it into a different sugar cube. If you allow chemical reactions, as in "how many ways can the contents of a sugar cube be used to make another substance?", then again, there are an infinite number if potential transformations. If you were to hurl a particular sugar cube into the ocean or the sun, in a thousand years, atoms from that cube would be found in several billion organisms.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Melting is a physical change; but when the temperature is sufficiently high sugar is thermally decomposed - and this is a chemical change.
Melting is a physical change.

Yes.Yes.Yes.Yes.
Yes, it is a chemical change.
Melting is a physical change.
Physical
The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
No.
