Depending on the value of this quantity, azeotropes are classified as "positive" or "negative".
Depending on the value of this quantity, azeotropes are classified as "positive" or "negative". A device for measuring this quantity is called an ebullioscope. This quantity increases as the pressure on a substance increases. Substances are separated based on differences in this quantity in distillation. A liquid whose temperature is higher than this quantity is said to be superheated. This temperature is colligatively increased when a solute is added to a liquid, and is highest for substances with strong intermolecular forces. For 10 points, name this temperature at which a liquid becomes a gas.
