As your altitude increases, the boiling point of water decreases. this chart to see if you are cooking at lower temperatures than expected. Did you know that high altitude affects water? This article provides a formula to calculate the relationship between water's boiling point vs. altitude. Also find. Elevation and boiling point of water. Sponsored Links. The boiling point of water decreases with altitude: Boiling point water (fahrenheit) versus altitude (feet ).
Does water’s boiling point change with altitude? Americans aren’t sure
Explain why or why not. When the information from both tables is combined, would a linear function be appropriate to model this data? What kind of function would you use to model the data? IM Commentary This task examines linear models for the boiling point of water as a function of elevation.

- Water Boiling Point vs. Altitude: With Boiling Point Elevation Examples
Two sets of data are provided and each is modeled quite well by a linear function. The slopes of the two linear models are different, however, and so a single linear function is not as accurate when the two sets of data are considered simultaneously.
It turns out that for the entire data set, an exponential model fits the data better than a linear model. One of the reasons linear models are so important is that they are relatively easy to construct and evaluate and even non-linear phenomena like the boiling point of water can still be modeled over suitable domains by several linear functions. We can see in several ways that the boiling point of water cannot be a linear function of elevation for a sufficiently large domain.
How do atmospheric pressure and elevation affect boiling point?
If the boiling point were to continue to decrease at a constant rate as we gain elevation, then it would eventually become less than absolute zero which does not make any sense.
Also, from a scientific point of view, a definition of the boiling point of water is the temperature at which ''the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure'' taken from http: This means that the variation of the boiling point of water is tied to the variation of air pressure which happens to be modeled by an exponential function.
Not surprisingly, the temperature at which water starts boiling is not constant and depends on pressurewhich in turn is dependent on altitude. In this article, we will present you with the boiling point elevation equation and explain in detain how to calculate the boiling point of water at any altitude.
How do atmospheric pressure and elevation affect boiling point? | Socratic
What is the boiling point? It is simply the temperature at which water starts boiling - in other words, it changes its state from liquid to gas. This temperature is dependent on pressure and the substance type. Hence, you can be sure that each sample of clear water will start boiling at the same temperature at a given terrain elevation.
Boiling point of water at sea level You don't have to use our boiling point at altitude calculator to determine the boiling point of water at sea level. Actually, the formula for boiling point uses this value as the basis of calculations. Boiling point elevation equation Remember that the boiling point of water depends solely on pressure.
High-altitude cooking - Wikipedia
This boiling point calculator finds the pressure at altitude assuming that the pressure at sea level is constant and equal to hPa 1. This approximation is sufficient for this kind of calculations. If you want to find more precise results, check out our air pressure at altitude calculator.
