Question

Write an activity in which water can be to boil even at a temperature below its boiling point ?

Answer 1

Water boils at 100 ^oC when the atmospheric pressure is 1 atm. Decreasing the atmospheric pressure will decrease the boiling point of water. And we know atmospheric pressure decreases with altitude.

So, if we take the water in a higher altitude and boil it, it will boil at a temperature below 100 ^oC.
