How does salt affect the boiling point of water? (in simple words)

Dissolving salt in water raises the boiling point (and lowers the freezing point).

I know that, but how would explain the process.

Salt affects the boiling point of water by raising it. When salt is added to water, it increases the concentration of particles in the water. This then leads to an increase in the boiling point. In simple terms, the presence of salt in water makes it harder for the water molecules to escape as steam, requiring higher temperatures to reach the boiling point.
