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 boiling water to cool 80 degrees?

5 minutesThis can be done by allowing the water to cool in the kettle after boiling but can take up to 5 minutes so not often practical. Pouring the fully boiled water into the pot or cup will allow it to cool quicker, generally reaching 80 degrees within a few minutes.

Can boiling water go above 100?

Liquid water can be hotter than 100 °C (212 °F) and colder than 0 °C (32 °F). Heating water above its boiling point without boiling is called superheating. If water is superheated, it can exceed its boiling point without boiling. … To experience this, put a container of bottled water into a bowl of ice.

What is the fastest way to cool down hot tea?

Why does water take so long to cool?

Compared to air or land, water is a slow conductor of heat. That means it needs to gain more energy than a comparable amount of air or land to increase its temperature. … That means that, once heated, a body of water will hold onto that heat for a much longer period of time than either air or land.

Can you make water boil at 70 C?

Yes, You can make water boil at 70° C. Since, the Water boils at 100° Celsius at level of the sea. Reduce the atmospheric pressure around the water, by using a vacuum pump and a closed container, else go into a very high altitude. This allows the water to boil at a lower temperature and many more liquids too.
