Why does it take a long time to boil water?

Compared to air or land, water is a slow conductor of heat. That means it needs to gain more energy than a comparable amount of air or land to increase its temperature. … That means that, once heated, a body of water will hold onto that heat for a much longer period of time than either air or land.

What happens to the boiling point of water at high altitudes quizlet?

How does a higher altitude affect boiling point? Atmospheric pressure is lower at high altitudes and the temperature is lowered for boiling. … Because they dilute the water molecules and lower vapor pressure.

Why does water take so long to boil at high altitude?

The key factor is declining air pressure at higher altitudes. Falling air pressure lowers the boiling point of water by just under 1 degree Fahrenheit for each 500 feet of increased elevation. The lower boiling point means water will cook off more quickly, and at a lower temperature.
