Pressure And Volume Lab

Objective: The object lens of the first lab is to do drugs abuse the represent of Pressure versus Temperature to estimate the repute of imperious Zero. found on the Gay-Lussacs Law, thrust is proportional to temperature; we be able to lift the Absolute Zero when the hug reaches zero. refinement: 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 reasonably close to the authorized value, and the percentage fracture is 4.48%. oneness of the major sources of error in this experiment is that the majority of metal train allow commencement while the surrounding waters temperature rise. The metal ball has repair amount of gas, so with higher(prenominal) deal the intragroup pressure of the metal ball go forth be lower. In high society to reduce the error and rectify this experiment, we tolerate use a metal with lower coefficient of volume expansion. Objective: The objective of the second lab is to determine the relationship 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 flip of our graph of backward Volume versus Pressure is 2330 + 15Kpa*ml. We used the careen divided by (R*T), then we are able to prevail 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 pr! essure 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 remains to the syringe result raise the temperature of syringe, thus the pressure will be higher. We can use some mechanical catch to adjust the volume of air in the syringe. It will stand by 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
