Intro Chemistry Lab I Dr. Pasternack 10/29/10 Experiment 6- Enthalpy of vaporization of water This report will have a full length lab report, worth about 14% of your grade. They will need to be submitted to your TA in lab and to turnitin.com The format is described on pages 9-13 in the manual. Do not leave out any sections. Vapor Pressure H 2 O(l)H 2 O(g); K=P(H 2 O(g)) You will calculate the vapor pressure of water as a function of temperature by measuring the volume of an air bubble as a function of temperature. From this, you can determine ∆H vap . Overview 1. Fill the graduated cylinder 2/3 full 2. Invert into a beaker of water 3. Reading on graduated cylinder should be 4-5ml 4. This fixes the number of air molecules 5. Heat the water in the beaker and observe the expansion of the bubble. Expansion due to heating air in bubble and water vapor, which increases with temperature P tot =P air +P vap Tips Bubble of 4.5mL at room temperature is best.
