The boiling point of water or any liquid depends on the temperature, pressure, and the vapour pressure of the liquid. That is, for example, a liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. Similarly, a liquid at high pressure will h...
Let's start with finding the boiling point of water if the air pressure is 245,675 Pa. We substitute the known air pressure value into the formula: ln245675101325=4890(1373−1boilingpoint) And solve for boiling point: Simplify fraction: ln(2.42)=4890(1373−1boilingpoint) Take the ...
What is the boiling point of water?Boiling PointThe boiling point of a liquid is the temperature at which it is sufficiently heated to begin transforming into a vapor. Every liquid has a boiling point, though the exact temperature differs depending on the liquid....

Water boiling point: 96.5 °C Air pressure: 898.8 hPa Altitude: Reading altitude failed (uses device pressure sensor) (uses device pressure sensor) (Ad supported freeware) Calculate the boiling temperature of water and the air pressure for your current elevation on earth or any other ...
water can boil at a much lower temperature. That is, body temperature would be sufficient to allow the blood to boil with water, if not for the skin that holds the blood pressurized. So, speaking of the boiling point of water, it boils at low air pressure at temperatures significantly bel...
Presents two problems related to the theories involved in the boiling point of water. Use of Clausius-Clapeyron equation to determine phases of solid-liquid, liquid-solid, solid-gas phase transition; Calculation on the melting point of water at an altitude above sea level; Required pressure to ...
