Answer 2

• The entropy of a solution is generally increased by spreading the solute molecules over a larger volume of the solvent.
• Entropy increases as a solid dissolves into an aqueous solution.

Process of  iodine change in entropy

• Iodine atoms have transitioned from a state of order (crystalline iodine) to a more disordered state .
• The entropy level will have risen.

Dissolving Process:

• The solute particles become isolated from one another when a solution is formed, increasing entropy.
• Entropy rises in lockstep with temperature.
• When the temperature of a substance rises, the kinetic energy of the particles increases.
