Pure Water Fahrenheit Research Paper

Pure water boils at 212˚ Fahrenheit (100˚ Celsius) at sea level, but water can also boil at temperatures as low as -90˚ Fahrenheit (theoretically). The reason for this phenomenon is pressure. “There is a direct correlation between pressure and temperature when it is dealing with the boiling point of water,” says Jacob Young, a mechanical designer at Blauch Brothers, Inc (Young, J.C. 2017). The pressure on Earth at sea level is 14.696 PSIA (Pounds per Square Inch Absolute). This pressure is caused by the weight of the Earth’s atmosphere being pulled towards Earth’s surface by gravitational forces. At this pressure, water’s boiling point is 212˚ Fahrenheit. Pressure decreases with increasing altitude, and as a result, the boiling point of water deceases as elevation increases. Since pressure and temperature are directly correlated to each other, when the pressure (PSIA) is …show more content…
Therefore, using the boiling point to show a direct correlation between pressure and temperature is more effective than using the freezing point. To lower the boiling point of water without changing elevation, a vacuum must be used. In this instance, the term vacuum is not referring to a vacuum used to clean a house, but an instrument used to lower the pressure of a closed system. The measurement of a vacuum is expressed as inches of hydrogen. As the pressure starts to decrease, the inches of hydrogen in a vacuum starts to increase. At 14.696 PSIA, the inches of hydrogen are at zero because a vacuum is not need to acquire the pressure at sea level or higher. To boil water at a temperature below 212˚ Fahrenheit, at sea level, a vacuum would be required because it cannot occur naturally. Another way to lower the boiling point of water is to boil it at a higher altitude, because pressure decreases as altitude
