What is the hottest water temperature humans can withstand?
These are, of course, just estimates.
TL:DR numbers: …
In water, the upper limit seems to be about 50 °C (122 °F) for short-term exposure; even a couple of degrees hotter, first- and second-degree skin burns become possible within minutes, and that’s clearly not a sustainable situation.

Why does boiling water stay at 100 degrees?
When the water’s vapor pressure equals the ambient air pressure, the water boils. At sea level, this occurs at 100°C. Additional heat added to boiling water does not raise its temperature, because it is providing the additional energy (the heat of vaporization) necessary for the 100°C water to become 100°C water vapor.
Does boiling water temperature stay same?
Temperature and Boiling In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling. For example, water will remain at 100ºC (at a pressure of 1 atm or 101.3 kPa) while boiling.
Do kettles boil at 100 degrees?
Yes. Generally the rule is, the higher your altitude, the lower the boiling point of pure water is. At sea level (0 metres), boiling point is, by definition, 100 degrees Celsius.
Does water get hotter the longer you boil it?
Boiling point depends on pressure. At sea level, water boils at 100 °C (212 °F) and freezes at 0 °C (32 °F). … The water may boil more vigorously and convert into steam more quickly, but it won’t get hotter. In fact, at the microscopic level, there may be cooler regions of boiling water.
