My 11 yr old daughter asked me the other day what the boiling point in Celsius degrees was since she was boiling water for her Ramen noodles. Before I could muster out an “I’m not sure,” my 9 year old daughter quickly answered with an answer of “100 degrees”.
A 9 year old just showed me up!! But I wasn’t going to admit that. Again, she recently learned it being in the 3rd grade. It kind of made me feel stupid that I didn’t know the answer to a simple question like that. So, I had to look it up for verification.
Let’s start with a definition of what a boiling point is. Per Wikipedia, a boiling point of an element or a substance is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid.
The boiling point of water is 100 °C (212 °F) at standard pressure. And if you ask what standard pressure is, it’s all based off of sea level. The higher the altitude, the boiling point temperature decreases because there is less pressure.
On top of Mount Everest, at 8,848 m elevation, the pressure is about 260 mbar and the boiling point of water is 69 °C. (156.2 °F). The boiling point decreases 1°C every 285 m of elevation.
Interesting!
