boiling point elevation

Dissolved substance effect

Boiling point elevation is the increase in a liquid's boiling point when a substance is dissolved in it.

Pure water boils at 100°C, but adding salt raises that temperature slightly.

The effect depends on the concentration of dissolved particles, not their identity—a principle useful in chemistry and cooking alike.
