Pressure And Volume Lab

Objective: The object lens of the first lab is to dose abuse the represent of Pressure versus Temperature to estimate the set of peremptory Zero. ground on the Gay-Lussacs Law, thrust is proportionate to temperature; we be able to lift the Absolute Zero when the twinge reaches zero. destruction: 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 more or less close to the authorized value, and the percentage flaw is 4.48%. whiz of the major(ip) sources of error in this experiment is that the majority of metal vagabond allow commencement while the surrounding waters temperature rise. The metal ball has repair amount of gas, so with high flashiness the intragroup pressure of the metal ball impart be lower. In post to reduce the error and emend this experiment, we tolerate use a metal with lower coefficie nt of volume expansion. Objective: The objective of the second lab is to determine the kind 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 pitch of our graph of backward Volume versus Pressure is 2330 + 15Kpa*ml. We used the toss divided by (R*T), then we are able to materialise 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 inv! ersely proportional to the volume with fixed temperature. One of the major sources in this experiment is that the contact of piece ashes to the syringe give raise the temperature of syringe, thus the pressure will be higher. We can use some mechanical artifice to adjust the volume of air in the syringe. It will uphold 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
