Phantom Lab Analysis

Purpose: To learn about the international system of units (SI), to become familiar with common lab equipment and techniques, to gain proficiency in determining volume, mass, length, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

I would guess that the surface area has been decreased and the diffusion distance for gas

6) The tape was used to measure gas accumulation in the balloon after 1minute. Measurement and qualitative observations were recorded.

The standard deviation of the mean area 〖(S〗_A) and standard deviation of the volume (S_v) are determined using the following equations

Procedure: Have you made any changes to the procedure? Please explain. If you made no changes, state so. (1 point)

1. Carefully measure the volume of the trapped gas using the graduations (markings) on the side of the container.

No significant differences between the mean hang times could be found. In the second experiment, the researcher found that helium and nitrogen, gases lighter than air, had longer hang times than air, while carbon dioxide and argon, gases heavier than air, had shorter hang times (see Table 2 and Graph 2). There were significant differences between the mean hang times. Both results were subject to statistical analysis. An ANOVA and a follow-up Tukey HSD test were used on both results in the stat software JMP. In the first experiment, the ANOVA and Tukey HSD test resulted in p-values all over 0.05, which means there were no statistical differences between the mean hang times. In the second experiment, the ANOVA and Tukey HSD test resulted in p-values all under, 0.05, which means there were statistical differences between the mean hang

5. Zoom Out by clicking on the green arrow next to the Save button. Click on the Stockroom and then on the Clipboard and select Balloon Experiment N2. Again, set the temperature, pressure, and moles to 298 K, 1.00 atm, and 0.300 moles, respectively. You may have to click on the Units button to change some of the variables to the correct units. Repeat the experiment with this gas labeling the data link ‘Real Gas N2.’

The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.

The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know, identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions, measurements, and weights to then calculate using algebraic formula.

6. The outflow rate is measured by using a measuring cylinder. It is measured 3 times and averaged for a more accurate result. The results are shown in Table 2.

Inflow from the tank was calculated using the known internal dimensions of the tank, the % full reading, and the time step which the data was collected.

Precautions: to ensure high quality of the data presented, precautions regarding data collection and instrument calibration will be followed (pressure transducers, cobra probes, laser sensors, and accelerometers, etc.). All data will be routinely checked for precision, accuracy and variability. Experimental procedures will be checked for accuracy and quality, and instruments will be calibrated. CFD models will be validated with experimental results.

The data needed will be obtained to examine the performances by considering the operational parameters of the system. Parameters of the systematic are operational power, primary inert gas, secondary inert gas, nozzle
