Does Making jelly involve dissolving?
Yes, making jelly involves dissolving ingredients, specifically the sugar and pectin, in fruit juice.

Heating the mixture helps dissolve these components thoroughly before cooling, which results in a gel-like consistency.

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.
