regarding the previous question I did in the other MATH contest about the multiples of the number 2.111.112.
The correct answer is infinite, but no humans answered :)

Thats correct!
(due to temperature difference inside outside, cooling down, loosing presure inside and so on and so on... well done!)

Unfortunatly wrong as you chosen the wrong answer, even with argumenting in correct direction.

"If you boil water at a higher pressure (below sea level, for example), the boiling point would be higher than 100 °C . At a lower pressure (like in the mountains), the boiling point is a lower temperature."

As we have a higher boiling point in lower areas the water just gets hotter before
transforming to gas - so egg is cooked faster :embarressed:
