* Physical Change: The process involves a physical change where the state of matter changes. The ice cube melts, transitioning from solid water (ice) to liquid water. This change in state does not involve the formation of new substances.
* Heat Transfer: The cooling effect is due to heat transfer. The ice absorbs heat from the drink as it melts, lowering the drink's temperature. This is a transfer of energy, not a chemical transformation.
* No New Substances Formed: The ice cube and the drink remain chemically the same. Water (H₂O) is the primary component of both, and no new chemical compounds are created.
In contrast, a chemical reaction involves the formation of new substances with different chemical compositions.
