Question
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 P and temperature T is expressed by the Clausius-Clapeyron equation ln P2/P1 = H vap/ R (1/T1 - 1/T2) where P1 and P2 are the vapor pressures at the absolute temperatures T1 and T2, respectively, Delta Hvap is the heat of vaporization of the substance in joules per mole, and R is the ideal gas constant, which is equal to 8.3145 J/(mol K). The heat of vaporization of water is 4.07 x 10^4 J/mol. The instruction booklet for your pressure cooker indicates that its highest setting is 12.7psi . You know that standard atmospheric pressure is 14.7 m psi, so the booklet must mean 12.7psi above atmospheric pressure. At what temperature in degrees Celsius will your food cook in this pressure cooker set on "high"?Explanation / Answer
