example experiment report for phys 342l the following report is written to help students in compiling their own reports for phys 342l class. note that this report does not represent a real experiment and thus should be used only as an example of style and form. the actual experiment reports will usually be longer as there is more material to cover.,chemistry 51 experiment 3 introduction to density,weigh a clean, dry 25-ml or 50-ml graduated cylinder. remove it from balance and add 15.0 ml of distilled water and read the volume to the nearest 0.1 ml (carefully observe the bottom of the meniscus). re-weigh the graduated cylinder now containing water. calculate the mass of water and the density of the water using the equation, d m/v.
the number of moles of air, n air, can be found by measuring the volume, temperature, and pressure of the trapped gas at a temperature near 0 c, where the water vapor content is less than one percent and can be neglected. 1 chemistry 212 vapor pressure of water h equation 2. 1 air r t p v n atm equation 1. p o p atm p air 2,experiment 14 introduction to thermodynamics,pressure vs. volume since the cylinder is uniform.) 8. use the ruler stuck to the side of the cylinder to measure height. see figure 2 below. add 200 g to mass to account for the mass of the piston and friction. plot mass vs. height and curve fit. part 4- ideal gas law 9. in the front of the lab is a container of
experiment 6 orifice and free jet flow. 1. introduction. an orifice is an opening, of any size or shape, in a pipe or at the bottom or side wall of a container (water tank, reservoir, etc.), through which fluid is discharged. if the geometric properties of the orifice and the inherent properties of the fluid are known, the orifice can be used,experiment 16 the solution is dilution,use this pipet to add 3.80 ml of the sucrose stock solution to the 10 ml graduated cylinder. now fill the graduated cylinder to the 10 ml mark with deionized water. mix the solution by agitating with the pipet or a clean stirring rod. transfer this solution to test tube 2.
use the pipette to ne-tune the meniscus. 13. carefully submerge the object in water and deter-mine its volume. 14. remove and dry the object, then empty the gradu-ated cylinder and invert it on a paper towel to dry. 15. determine f b on the object with eq. 10.2. 16. calculate obj using eq. 10.5 obj m v (10.5) use the volume,pin fin lab sample report university of washington,apr 12, 2017 throughout this example report the heat transfer rates q are calculated from the second approach using fouriers law. 4.2. estimate h values using an overall heat balance on the fin and an average fin surface temperature for both the natural and forced convection cases.
6. select another cylinder and repeat steps 2-5 until you have measured the mass and diameter of 4 cylinders. 7. the density lab program is designed to calculate the volume and density of the brass cylinders using your data. consult with your lab instructor if the program does not produce valid solutions with your data. 8.,analysis of experimental uncertainties density,1. select the tab entitled data sheet for cylinders. all measurements performed using cylinders will be recorded on this spreadsheet. 2. select one of the brass cylinders and measure its mass using the scale. record this in the mass column of the spreadsheet. 3. follow the procedures outlined for using the electronic digital caliper and measure
the cylinder was quickly inverted and the end placed under water in a 400 ml beaker filled with water. the reaction was initiated by the diffusion of the hcl to the metal and gas was captured in the inverted cylinder. when the reaction ceased, the levels of water in the cylinder and beaker were equalized and the volume of gas determined.,experiment 1 university of idaho,lab 2 calibrate your glassware. during this lab period you will need to check out one or more items from lab services. sometimes long lines can develop at lab services, especially in the afternoon sections. if there is a long line, start working on the parts of the experiment you can

the problem is that you cant directly measure n initial or n final (the air molecules are invisible and there are way too many to be counted anyway). this experiment is set up in such a way that the pressure of the air in the air sample remains constant even though the oxygen is being removed from the sample (water moves into the graduated cylinder as the o 2 is removed which decreases the,lab report 2 impact of pipetting technique,lab report 2 impact of pipetting technique. 21. 1. 0. the pipette is a reliable precision instrument that has been used and trusted for many years. however, as with many forms of instrumentation, a pipette will perform only as well as the operators technique allows. differences in technique some more than others can alter delivery
