The Formula for Boiling Point. It are often calculated as: Kb = RTb2M/ΔHv, R is that the universal gas constant. Tb is that the boiling temperature of the pure solvent [in K] M is that the molar mass of the solvent. ΔHv is that the heat of vaporization per mole of the solvent.

References. External links. Boiling point. Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. 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.
26 de may. de 2024 · ln (P₁/P₂) = -ΔH/R × (1/T₁ − 1/T₂) where: P₁ — Pressure at state 1; P₂ — Pressure at state 2; T₁ — Boiling point at state 1 (at a pressure equal to P₁ ); T₂ — Boiling point at state 2 (at a pressure equal to P₂ );
12 de abr. de 2024 · The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).

The formula of each entry is followed by its formula weight in parentheses and the boiling point in degrees Celsius. First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules.
ΔTb = Tb(solution) −Tb(solvent) = Kb × m (1) (1) Δ T b = T b ( s o l u t i o n) − T b ( s o l v e n t) = K b × m. where ΔTb Δ T b is the boiling point elevation, Kb K b is the boiling point elevation constant, and m is the molality (mol/kg solvent) of the solute.
