29 Ιουλ 2024 · Our boiling point calculator uses the Clausius–Clapeyron relation to establish the boiling point of any substance at a given pressure. This equation characterizes phase transitions (such as vaporization) and relates the pressure to boiling point in the following way: ln(P₁/P₂) = -ΔH/R × (1/T₁ − 1/T₂) where: P₁ — Pressure at ...

30 Νοε 2022 · With our boiling point calculator, you can quickly determine the atmospheric boiling point of various substances. You may also calculate the boiling point at different pressures.
What is a boiling point? The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure, thus facilitating transition of the material between gaseous and liquid phases. All boiling points below are normal/atmospheric boiling points: they give the temperature at ...
To convert Celsius to Kelvin simply add 273.15 to the value. For example, if you had a temperature of 25 degrees Celsius, add 273.15 to this as follows: 25 + 273.15 = 298.15K. For every change of a degree Celsius, it is equivalent to a change of one degree in Kelvin.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.
The kelvin is the same size as the Celsius degree, so measurements are easily converted from one to the other. The freezing point of water is 0°C = 273.15 K; the boiling point of water is 100°C = 373.15 K. The Kelvin and Celsius scales are related as follows: \[T\; \ce{(in \;°C)} + 273.15 = T\; \ce{(in\; K)} \label{7S.1a}\]
The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below:
