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.
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.
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.
Yes.Yes.Yes.Yes.
A physical change because the substance does not change. It is still H2O, but in a different form.
Yes, it is a chemical change.
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.
Melting is a physical change.
This is a physical change the chemical composition of the sugar does not 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.
Freezing is a physical change.

no that is a physical property change, not a chemical property.
it is a chemical
It is a physical change because if the H2O
