"Vapor Pressure of Water" assignment:
VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...

Find P air and V air ..
Water vapor accounts for part of the gas volume and S8 lle volum u sued must be corrected for the water vapor present. The vapor pressure of the water depends on temperature and the vapor pressure of water (PH,o) at different temperatures can be found in Table 1. If a Ph,o value at a particular temperature is not usted in the table, then it has to be found through the interpolation method from...
