How long does it take for boiling water to reach room temperature? Cooling from 100 to 45 in a closed container, not sealed so you don't get a vacuum, probably takes 100 minutes or so. 50–45 20 min , but you said open pot, so it's faster, as you get material loss (evaporation/”sensible heat”) as the water cools.
How long does it take water to go from boiling to room temperature?
The cooling rate will also depend on the mass (volume) of the water, the mass of the pot, the thermal transfer capacity of the pot and anything it contacts, ambient temperature, air pressure, humidity, purity of the water, etc. The answer to your question is “close enough”. I'd wait about 30 seconds .

Can boiling water go above 100?
Water Hotter Than Boiling Point and Colder Than Freezing Point. Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). ... If water is superheated, it can exceed its boiling point without boiling. You may have firsthand experience with the phenomenon, as its fairly common when microwaving water.
What temperature do kettles boil to?

What's the hottest you can boil water?
Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F) .
Will water get hotter than 212 degrees?
It is not true that water can only get up to 212 degrees and as cold as 32 degrees. After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that.
Is it OK to leave water in a kettle?
Leaving water inside the kettle will result in limescale that will not only ruin the taste of hot beverages but will contribute to the shortened lifespan and weakened heating performance of the kettle.
Why does my kettle turn off before it boils?
If you have a kettle that turns itself off before the water gets hot enough, most of the time, it's because of a faulty thermostat . ...
