Charles’ Law and Absolute Zero

Date of experiment November 4, 2010 Date submitted November 11, 2010 entry As per Charles Law, there is a unidimensional relationship in the midst of the temperature and volume of a gas. Charles discovered that -273C is the point at which a gas has no volume. Since thats as cold as he musical theme things could ever bilk, that originated the idea of absolute cryptograph. In this experiment, Charles Law was applied and made into info to determine an experimental value for tyrannical Zero. To do so, a fixed add together of gas was confined in a exquisite, uniform sample tubing.The temperature of the gas was changed, by being placed in body of peeing. The expect result is that as the temperature of the gas gets tank (decreases), the volume of gas will decrease. military operation A 400mL beaker was pretend practiced with tap pee and place on a stifling plate until the thermometer read 55C. and so a sample tube filled with devil hydrargyrum stopples was obtained fr om the instructor. With a ruler, the hold among the two mercury plugs was recorded. development low-toned rubber bands, the sample tube was strapped to the ruler, which was and because attached to the bottom of thermometer.A phellem was attached onto the top of the thermometer, and then clamped in the beaker of pre-heated water. The initial temperature and distance between distributively plug in the pre-heated water were then recorded. Ice was added and stirred every so often to cool the temperature of the water. When the beaker was going to overflow, small amounts of the water were removed by a pipet. The temperature and distance between each plug were then recorded every two minutes. Eight sets of temperatures were recorded when the goal temperature of 0. C was achieved. Data 1) Temperature and space Between hectogram Plugs Every 2mins Time (minutes) Temperature of water (C) Distance between plugs (mm) 0 (Plugs out of water) 49. 8 60. 2 (in room temp) 2 (Plugs in water) 4 6. 3 63. 8 4 42. 2 63. 3 6 39. 3 62. 2 8 24. 9 60. 0 10 19. 1 58. 6 12 7. 8 56. 6 14 1. 9 55. 1 16 0. 1 54. 4 18 0. 1 54. 4 Calculations 1) Line of crush fit y=0. 1981x+54. 752 Slope (m) 0. 198 mm/C Y-Intercept (b) 54. 8 mm 2) autocratic zero (V=0) -276. 8C 3) % geological faultExcepted value -273C Discussion My results lay out that as the temperature of the water decreased, the distance between the two mercury plugs decreased. This supports Charles Law which states . When creating my graph, I did not include the first initial temperature and length recordings. The plot was not anyplace near the others, and would have thrown move out the slope. My value for absolute zero was evenhandedly close to the excepted -273C. There was a small difference of 3. 8C between the two values, with a percent defect or 1. 4%.My results were expected because I was obviously not going to get the perfect -273C absolute zero value, due to experimental misconduct. Sources of experimental error tha t could occur are if the initial temperature of the water was over 55C and if the mercury plugs were not fully submerged in the water. If the water was over 55C, then the ruler would have deformed from melting. This would make the rulers readings unreliable. If the mercury plugs were not fully submerged in the water then they would not get the full effect of temperature change.
