Expansion Processes of a Perfect Gas

Assignment:

1. Attend the laboratory class and complete the lab tests according to the supervisor's requirement. Students will not allowed to submit their report if they do not come to the lab class.

2. Write one about 2000-2500 word report and submit it by the due time. In the report, you need to do the following analysis.

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 -40° to 50°. 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 equipment includes A common base plate (4) Top plate (2)
Large vessel (3)
Small vessel (6)
Air pump (9)
Pressure sensors (P & V)
Sensor P measures the pressure inside the larger pressure vessel (3)
Sensor V measures the vacuum inside the smaller vacuum vessel (6) (Positive values for vacuum pressure)
Temperature sensors T1 and T2 inside each vessel Valves

V1 - the large vessel to atmosphere
V2 - the large vessel to the small vessel (via a large bore pipe) V3 - the small vessel to atmosphere
V4 - pump to the large vessel (pressurize the large vessel)
V5 - needle valve connecting the large vessel to the small vessel V6 - the large vessel to the small vessel (via needle valve V5)
V7 - pump to the small vessel (the pump draws air from the small vessel)

Test A - Determination of Heat Capacity ratio (Specific heat ratio)

Test B - determination of ratio of volume using an isothermal process

Attachment:- Lab.zip

Verified Expert

The paper is about expansion process of perfect gas with the help of experiment. In Test A it discusses to find the specific heat ratio in three stages initial pressure, intermediate pressure and final process. In Test B four experiments have been conducted to check the temperature process and change in volume to satisfy the Boy’s low of perfect gas equation.

Results (40%) 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 (20%) Based on the results obtained from the test, a student needs to discuss what are the outcomes of the tests. Writing (10%) The writing needs to be logical, clear, concise.
