Solubility is forming of chemical bonds between solute molecules and solvent molecules, hence a chemical reaction.
A chemical change is the same as a chemical reaction.
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
No. If one substance does not change into another, it is not a chemical change.
Roasting a marshmallow is a physical change, not a chemical change. The marshmallow undergoes a change in its physical state as it is heated, but its chemical composition remains the same.

No, the chemical composition is still the same.
it is a chemical change
A chemical has changed appearance in both a physical and chemical change. It cannot stay the same or it wouldn't have changed.
They are just two different terms that mean the same thing.
No, it is a physical change because the water is the same but just boiled
no its not true
physical change since the egg and the contents inside do not become a new substance they remain the same only thing is that the shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because its internal composition is the same
