Boiling Point of Liquids Chart
Boiling points of common liquids at standard atmospheric pressure (1 atm), from liquid nitrogen to glycerol.
Boiling points at 1 atm
| Liquid | °C | °F |
|---|---|---|
| Liquid nitrogen | -196 | -320.8 |
| Propane | -42 | -43.6 |
| Ammonia | -33.3 | -27.9 |
| Butane | -0.5 | 31.1 |
| Diethyl ether | 34.6 | 94.3 |
| Acetone | 56 | 132.8 |
| Methanol | 64.7 | 148.5 |
| Ethanol | 78.4 | 173.1 |
| Isopropyl alcohol | 82.6 | 180.7 |
| Water | 100 | 212 |
| Ethylene glycol | 197 | 386.6 |
| Glycerol | 290 | 554 |
| Mercury | 356.7 | 674.1 |
Notes
A liquid boils when its vapor pressure equals the surrounding pressure, so boiling points fall at altitude (see the boiling point by altitude calculator) and rise in a pressure cooker. Liquids with low boiling points evaporate quickly at room temperature and are often flammable — handle them with ventilation and away from flames.
Frequently asked questions
What is the boiling point of ethanol?
78.4 °C (173.1 °F).
What is the boiling point of acetone?
56 °C (133 °F).
What is the boiling point of liquid nitrogen?
−196 °C (−321 °F).
Why does alcohol evaporate faster than water?
It has a lower boiling point and higher vapor pressure.
Does salt raise the boiling point of water?
Slightly — a typical pinch of salt raises it by a tiny fraction of a degree; it would take a lot of salt to make a noticeable difference.
Why does a pressure cooker cook faster?
At 15 psi above atmospheric pressure, water boils at about 121 °C (250 °F), so food cooks at a higher temperature.
