|
Atmospheric pressure is lower, so it it takes less energy for water to reach its boiling point.
|
|
|
Atmospheric pressure is higher, so it takes more energy for water to reach its boiling point.
|
|
|
Temperature is lower in higher altitudes, so water reaches its boiling point faster.
|
|
|
Temperature increases as you increase in the troposphere, so water reaches its boiling point faster.

Detailed explanation-1: -It takes less energy to raise water to the boiling point when air pressure is lower. Because there is less energy and thus less heat at a higher altitude, water will boil at a lower temperature.
Detailed explanation-2: -At higher pressures (such as the pressure generated in a pressure cooker), the temperature must be higher before the vapor pressure reaches the surrounding pressure, so water under pressure boils at a higher temperature.
Detailed explanation-3: -The boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. A liquid boils when its vapour pressure exceeds the local total pressure. As the atmospheric pressure drops, the Vapour pressure increases more than the local pressure at an even lower temperature.
Detailed explanation-4: -At a higher altitude, atmospheric pressure is lower it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.
Detailed explanation-5: -With that much less pressure, you don’t need to apply as much heat to push vapor pressure beyond the surrounding atmospheric pressure – in other words, water boils at a lower temperature.
