yes, theres is not change to it's molecular structure
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.
Physical.
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
No, dissolving a sugar cube in water is a physical change, not a chemical change. The sugar molecules simply disperse in the water, breaking apart but not undergoing a chemical reaction to form new substances.

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.

This is a physical change the chemical composition of the sugar does not change

Dissolution is a physical process.
Yes.Yes.Yes.Yes.
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.

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.
