What is the Vapor Pressure of Water Calculator & How does it work?
The vapor pressure of water is a fundamental concept in physical chemistry, representing the pressure exerted by water molecules that are evaporating from a liquid surface into its vapor phase. This property is crucial for understanding various phenomena such as boiling and condensation.
The Antoine equation is commonly used to estimate the vapor pressure of pure substances like water over a wide range of temperatures. The equation is given by:For water, typical values for the Antoine equation constants are: A = 8.07131, B = 1730.63, and C = -233.426.
The Antoine equation is commonly used to estimate the vapor pressure of pure substances like water over a wide range of temperatures. The equation is given by:
\log_{10} P = A – \frac{B}{T + C}
P = vapor pressure in mmHg
A, B, C = constants specific to the substance
T = temperature in °C
A, B, C = constants specific to the substance
T = temperature in °C
