A place, not an object. Also kettles don’t hit 100. The water inside gets to 100. Actually let me add a side note. Depending on where you are in the world as well as the water you use it might not even hit the full 100.
That’s just saying that the heat is dissipating at the bottom of the heating element, in this case the kettle. The heat is moved by convection by the air molecules, then conduction by the kettle, then convection again by the water.
But for the water to reach the boiling temperature, it needs the underside of the kettle to reach its boiling temperature too. At sea level that would be 99.8C / ~100C, but at higher altitudes, it’s less.
If the kettle did not reach the boiling temperature, the first law of thermodynamics would not be upheld: the total energy of an isolated system is constant aka conversation of energy. The water must reach a boiling temperature and the only item between the flame and the water is the kettle. If the kettle didn’t reach the boiling temperature of water, the water would need to get the higher energy from another heat source. Without such an additional heat source, it would thus be getting it from the void, which would allow the creation of perpetuum mobile.
Also, the paper cup doesn’t burn because it is thin enough to convect the heat to the water and thus not reach its combustion temperature (233C). It still reaches the boiling temperature of water for the reasons states above.
Where do you live? On Venus? At 100 degrees water evaporates!
*just under 38c lol
Fahrenheit
Only a small minority of the world uses Fahrenheit… Why wouldn’t we automatically assume temperatures are in Celsius?
Because 100c is not a reasonable outside temperature
Where in the world have you ever witnessed hitting 100c?
A kettle?

Bruh, wat? How do you think the water gets to 100C if the kettle doesn’t hit 100C?

And this one is lengthy but it explains why. uses F for measurement units but it’s still gets the point across.

And finally a live demonstration of the paper cup used for boiling water

And this video wraps up just boiling water nicely

P.S thanks for the videos. They were interesting!
