Assignment - Expansion Processes of a Perfect Gas
Test A -
Draw the capacity ratio v.s. pressure graph. Discuss how well the results obtained from the lab compared with the expected results (you should find the exact heat capacity ratio yourself from library, internet or some other sources), by putting the test results and the expected results in the same graph. Explain the reasons for any difference.
The exact heat capacity ratio varies between 1.399 and 1.401 for temperature in the range of -40o to 50o. You may use 1.4 as the exact heat capacity ratio in your report.
Discuss why the initial expansion process can be considered adiabatic?
Test B -
Discuss
How well the result obtained compared to the expected result? Give possible reasons for any difference. The exact volumes of the large and the small vessels are 22.4 and 9.1 litres, respectively.
Comment on how the rate of change affects the temperature of the air inside the vessels.
The report will be assessed based on the following criteria.
Introduction and conclusion - This section outlines the aims of the laboratory tests and the main outcomes of the report. The purpose of the report needs to be clearly stated. In the conclusion section, the main outcomes of the laboratory test need to be summarized.
Description of the methodology - A student needs to present the methodology, describe the test procedure and explain the basic theory using their own words. It is not acceptable to copy from the lab note.
Results - This is the main part of the report. It will be assessed based on whether all relevant data are presented, how well the data are organized, how well charts and tables are presented, whether the methods for generating the data are correct and if a student show a good understanding of the fundamental theory. If a student makes fundamental mistakes, he/she will lose a significant percentage of marks.
Discussion - Based on the results obtained from the test, a student needs to discuss what are the outcomes of the tests.
Writing - The writing needs to be logical, clear, concise.
Conduct experiments in a large vessel and small vessel that images are attached.
For Test A also As shown in pdf we have to find Cp/Cv = (lnPs-lnPi) / (lnPs-lnPf) of all 7 value that we give in the table and also the equation of Cp/Cv that was given in to PDF. You take the value of Ps and Pf and Pi from the table which attached in a word file.
That value Cp/Cv that we find on that value we have discussed what is outcome test and compare theoretical value Cp/Cv 1.39 to1.40.
For test B V1/V2= (P2s-Pf)/ (Pf-P1s) used this equation for all value that in table B. And give a possible result for a different outcome and also how the rate of change affect the temperature.
