Pressure And Volume Lab

Objective: The object lens of the first lab is to medicate abuse the represent of Pressure versus Temperature to estimate the shelter of sacrosanct Zero. base on the Gay-Lussacs Law, thrust is proportional to temperature; we atomic number 18 able to lift the Absolute Zero when the pull reaches zero. terminus: Our observational terminus is -285.40 C. It content when pressure reaches zero, the temperature should reach -273.15 C, which is the value of Absolute Zero. Our experimental Absolute Zero value is clean close to the authorized value, and the percentage faulting is 4.48%. angiotensin-converting enzyme of the study sources of error in this experiment is that the majority of metal turn over allow commencement while the surrounding waters temperature rise. The metal ball has repair amount of gas, so with high deal the intragroup pressure of the metal ball ordaining be lower. In indian lodge to reduce the error and advance this experiment, we tolerate use a metal with lower coefficient of volume expansion. Objective: The objective of the second lab is to determine the race between the pressure and volume of gas with fixed temperature. Based on the Bayles Law, the pressure of the gas is inversely proportional to the volume with fixed temperature.

Conclusion: Our experimental result shows the set up of our graph of backward Volume versus Pressure is 2330 + 15Kpa*ml. We used the pitch divided by (R*T), then we are able to realize value of n which is n=9.50*10^-4. Our graph is a linear line, which means the product of pressure and volume is a constant (value of slope). so we are able ! to find that the pressure of gas is inversely proportional to the volume with fixed temperature. One of the major sources in this experiment is that the contact of piece dust to the syringe will raise the temperature of syringe, thus the pressure will be higher. We can use some mechanical crook to adjust the volume of air in the syringe. It will ease to prevent the human body contact, thus to avoid error and improve the experiment.If you deficiency to get a full essay, order it on our website: OrderCustomPaper.com
