The vapor pressure of a liquid is the pressure exerted by its vapor when the liquid and vapor states are in equilibrium. The relationship between vapor pressure and temperature is expressed by the Clausius-Clapeyron equation.
where and are the vapor pressures at the absolute temperatures and , respectively, is the heat of vaporization of the substance in joules per mole, and is the ideal gas constant, which is equal to 8.3145 . The heat of vaporization of water is .
The instruction booklet for your pressure cooker indicates that its highest setting is 11.9 . You know that standard atmospheric pressure is 14.7 , so the booklet must mean 11.9 above atmospheric pressure. At what temperature in degrees Celsius will your food cook in this pressure cooker set on "high"?
