The statement which best describes the difference between dissolution and melting is that dissolution involves the formation of a new substance, while melting involves a state change and is denoted as option A.
This is the process in which a solute dissolves in a solvent such as water to form a solution thereby resulting in a new substance being created.
Melting on the other hand is the process in which a solid phase is changed into a liquid phase with the application of heat which makes the atoms move more freely.
This is therefore the reason why option A was chosen as the most appropriate choice.
