Vapor Pressure Calculator. Blue fields allow input. The form below contains input fields, and read-only fields for output. Press <RETURN> or <TAB> to calculate. Accuracy: For many substances, vapor pressures are only poorly known; expect errors up to a few 10% of the vapor pressure value.
26 cze 2024 · This vapor pressure calculator uses the Antoine equation to calculate the vapor pressure of various chemicals (given in dropdown menu) with predefined Antoine coefficients (A, B, C) and temperature (in degrees Celsius), the calculator displays the vapor pressure in mmHg. Antoine Equation for Vapor Pressure Calculator. Chemical: A: B: C: Temp (°C):
The Clausius-Clapeyron Equation helps determine the boiling point of a substance at different pressures by describing how vapor pressure changes with temperature. The boiling point is reached when the vapor pressure equals the external pressure.
This empirical formula relates the vapor pressure of a pure substance to its temperature and provides an accurate prediction of vapor pressure over a range of temperatures. Antoine Equation: \ ( \log_ {10} (P) = A – \frac {B} {C + T} \) Where: P is the vapor pressure (in mmHg). T is the temperature (in degrees Celsius).
