Cesar Flores LAVC Chemistry 101 July 22, 2023
In this lab a volatile liquid will go to vaporization process which will be constant under given temperatures. After vaporization process the molecules go through liquid phase through condensation process. The partial pressure of a volatile gas is its vapor pressure at that given temperature. The vapor increases as the temperature increases. The enthalpy of vaporization will be found using the formula between pressure and temperature. Both temperature and pressure readings will be plotted on a graph. The slope of the line will be the negative enthalpy of vaporization over the gas constant.
