Yes.
Melting a sugar cube is a physical change because the substance remains sugar, just in a different form (solid to liquid). The chemical composition of sugar does not change during the melting process.
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.
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.
No, the dissolving of a sugar cube is a physical change, not a chemical change. The sugar molecules are still the same chemically; they are just dispersed in water instead of being in a solid form.
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.
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 a sugar cube is a physical change because the substance undergoes a change in state from solid to liquid without altering its chemical composition.
your mom's thong xD
Due to their varying melting points (ice 32 and sugar 366°)
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.
Melting is a physical change.
Melting is a physical change.
The liquid that comes from melting a sugar cube is caramelized sugar. This occurs when sugar is heated to a high temperature, causing it to melt, darken in color, and develop a rich flavor.
Yes, exactly.
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.
