* Boiling Water: When water boils, it transitions into a liquid state with a higher temperature. This higher temperature increases the kinetic energy of the water molecules, allowing them to more effectively break apart the ionic bonds holding the sodium and chloride ions together in salt. The dissolved salt ions then become surrounded by water molecules, effectively dissolving the salt.

* Steam: Steam is water in its gaseous state. The molecules in steam are far apart and moving rapidly, so they don't have the ability to interact with and surround the salt ions like water molecules in liquid form do. As a result, salt cannot dissolve in steam.
