Introduction and Procedure Procedure I A gas pis

A gas piston was filled with 100 mL methane gas (CH4). A thermometer was attached, and set to read oKelvin. The temperature and volume of the gas were recorded. The piston was placed in a constant temperature bath and the temperature set to æice.Æ When the gas temperature had stabilized, the temperature and volume of the gas was recorded. The temperature of the bath was then changed to 40C, and once the temperature of the gas had stabilized, the volume and temperature of the gas were recorded. Measurements were repeated at 60C, 80C and 100C

A candle was affixed to the bottom of a small pan with chewing gum, and enough water was added to the pan to cover the bottom to a depth of 1-2cm. The water temperature was 22C. The candle was lit, and a test tube placed over it so that the lip of the test tube was under water, and the apparatus was observed. The experiment was repeated with the water temperature at 36C,

4. The CharlesÆ Law constant, using a graph with temperature in Kelvin on the x-axis and volume in mL on the y-axis, is 0.34.

5. Extrapolating from the graph, the volume the gas sample would occupy at 50C is 133.1 mL, and at 120C it would occupy 319.38mL.

6. Since CharlesÆ Law is a constant for a fixed amount of gas at a fixed pressure, it would not matter which gas was used in Procedure I, step 2.

1. AS the candle burns up the oxygen in the test tube, and water is formed, the air pressure in the tube is decreased and so the water rises in the tube to bal
