* Kinetic Energy and Molecular Motion: Heat increases the kinetic energy of water molecules, causing them to move faster and vibrate more intensely.
* Breaking Bonds: The increased motion disrupts the bonds holding salt crystals together (ionic bonds between sodium and chloride ions).
* Solvation: As water molecules move around salt crystals, they surround the ions, pulling them away from the crystal lattice. This process, called solvation, is more efficient at higher temperatures because the water molecules have more energy to break the bonds and surround the ions.
* Increased Solubility: The increased solvation due to higher kinetic energy leads to a higher concentration of dissolved salt in the solution, meaning the salt dissolves better in hot water.
In summary: Hot water provides more energy for water molecules to break the bonds in salt crystals, allowing more salt to dissolve.
