FAQ
Frequently Asked Questions
Not exactly. Boiling point typically refers to a pure substance. Bubble point is used for mixtures and is the temperature at which the first bubble of vapor appears.
It is crucial in chemical engineering, petrochemical refining, HVAC (refrigerant mixtures), and any process involving distillation or phase separation of liquid mixtures.
The opposite is the 'dew point', which is the temperature at which the first drop of liquid condenses from a vapor mixture.
In very technical jargon, it is sometimes used verbally (e.g., 'The mixture bubbles point at X degrees'), but this is rare. It is primarily a noun compound.
The temperature at which the first bubble of vapor forms in a liquid mixture at a given pressure.
Bubble point is usually technical/scientific in register.
