Is it correct to say that dissolving a packet of juice powder in water makes a new substance such as fruit punch so it must not be a physical change?
The change is a physical one because the powder is simply dissolving into the water, and it could be powdered again by removing the water again. The physical properties of the fruit punch are very different, but not a chemical change unless there is a new substance created or precipitated.

How could you prove to someone that the dissolving was a physical to change not a chemical change?
You can demonstrate that dissolving is a physical change by showing that the chemical composition of the substance remains the same before and after dissolving. This can be done by evaporating the solvent and obtaining the original substance in its solid form. Chemical changes involve a change in the chemical composition of the substances involved, leading to the formation of new substances, which is not the case in dissolving.
