The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.
29 lip 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 ...
15 lip 2023 · If this pressure is the standard pressure of 1 atm (101.3 kPa), then the temperature at which the liquid boils is referred to as its normal boiling point. This is the boiling point which is usually quoted in chemical literature.
23 sty 2023 · This web page explains the factors that affect the boiling points of organic compounds, such as molecular mass, intermolecular forces, and polarity. It does not provide a boiling point equation or a formula for calculating boiling points.
27 lis 2016 · Learn how to calculate the boiling point of a liquid using the Clausius-Clapeyron equation and the boiling point elevation equation. See examples, applications and history of boiling point.
A compound's boiling point is a physical constant just like melting point, and so can be used to support the identification of a compound. Unlike melting points however, boiling points are not generally used as a gauge of purity.
30 lis 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.
