Unformatted text preview: Josh Magnuson February 23, 2005 Chemistry 535 3 rd Hour Mr. T Charles Law: The Effect of Temperature on Volume Purpose: To determine the effect of temperature on the volume of gas when the pressure is constant and use the volume and temperature to calculate a constant showing the relationship between the values. Problem # 1. Trial One Trial Two Initial Temperature of Water T1 101.5 C 66 C 374.5 K 339 K Final Temperature of Water T2 26 C 26 C 299 K 299 K Volume of Water in Flask after the Experiment 88 34 Total Volume of water in the Flask V1 110 110 Final Volume of the Gas (4-3) V2 22 78 Atmospheric Reading P1 764.04 mmHg 764.04 mmHg 101.4 kPa 101.4 kPa Vapor Pressure of Water at T2 P2 25.209 mmHg 25.209 mmHg 4.01 kPa 4.01 kPa Pressure of the Dry Gas 738.83 738.83 Volume of the Dry Gas 827.85 827.85 Problem # 2a. Instruments used: 250 mL Beaker-used to boil water in so flask can build up gas to prove Charles Law 100 mL Volumetric Flask-put in beaker and heated up for 3 minutes to prove Cs Law #00 one hole stopper-put into flask to plug hole and make sure no gas escaped...
