This phenomenon is known as boiling point elevation, which is a colligative property. Colligative properties depend on the number of solute particles in a solution, not on their chemical nature. The presence of solute particles lowers the vapor pressure of the solvent, requiring a higher temperature to reach the boiling point (where vapor pressure equals atmospheric pressure).
A non-volatile solid is added to water. Its boiling point will
