From the ‘Results’ section above, as the roughness of a surface increases, the coefficients of friction for the block of wood increases. This can be concluded as the surfaces used in order of lowest roughness to highest roughness were the white surface, wooden surface and lastly the sandpaper surface had coefficients of friction increasing in the same order. For instance, to compare the static coefficients of the first trial of each surface in order of roughness, 0.20< 0.32. Therefore, corresponding with the coefficients of static friction, the coefficients of kinetic friction also increases as the roughness of the surface increases. In conclusion, from the data collected, the observation was that as the roughness of a surface increases, the coefficient of static friction and the coefficient of kinetic friction for a block of wood will increase.

9. Select one of the following terms to describe the crystal shape, or habit, or each specimen shown in Figure 1.8 (p. 6 lab book): cubic crystals, hexagonal crystals, fibrous habit, banded habit, blocky habit, bladed habit, tabular habit.

Part 1: Obtain some 0.200M Fe(NO3)3 solution and some 0.00020M KSCN solution. Starting from the first solution, pour and mix 8.0mL of Fe(NO3)3 solution and 2.0mL of KSCN solution into a test tube, where as the second solution has 7.0mL of Fe(NO3)3 solution and 3.0mL of KSCN solution. Continue this process until 5 test tubes have been filled. Pour

We have also performed Camera assembly modifications by strengthening and increasing the camera lens channel in order to add silicon ring for better sealing. We Followed by Lasers wires path improvement and decreasing the laser triangle size in order to maintain small dimension of the overall product.

The EDS elemental mapping of the sample are shown in Figure 3-14. It can be seen that a layer of Al starts to be shaped between two layers of Ti. As it was shown earlier in Figure 2-10, the first transition time is around 1second after machining. It can be

We packed the powdered alum into a capillary then dropped it onto the lab table to make it move to the bottom. My group then strapped the tube onto a thermometer using a rubber band. Next, we clamped the thermometer with the capillary tube onto a ring stand with a rubber stopper. We dipped the thermometer and tube into a Thiele melting point tube that held silicon oil inside of it. My group heated the tube with a bunsen burner and waited for the powdered alum to melt from the capillary tube. We recorded the temperature at which the alum disappeared from the tube to get our melting point. This whole process was repeated to find a more accurate melting point than the first

The digital microscope Keyence VHX-5000 is a method, which is easy to handle and supports research with high-resolution images and the calculation of 3D-surface-models. Several functions make it easy and quick to work with: The 3D-function also allows clear 2D images of a rough surface, because all levels are focused automatically and a sharp image of all levels will be created. This function makes it easy to analyse deep cuts, which can be only partially focused in light microscopy or electron microscopy. To calculate a 3D- surface-model the lower and upper border of the depth of interest has to be determined, by focusing on these levels. Between these borders a level difference of five microns were chosen. In other words, after every scan the lens moves five microns from the sample away.

In conclusion this investigation highly increased my knowledge on the use of spectrophotometer and other lab techniques and as a first timer the final result of 39% which was 6% off the expected value was not bad. I believe that for next time if all the limitations I stated are taken care off, then the value of 45% is easily

The results of this experiment helped understand the concept of absorbance, transmittance and concentration. Table 1 illustrates the percent transmittance, transmittance, and absorbance of the made solutions. The percent transmittance was found by placing each test tube in the Spec20 and recording its value. The transmittance is how much light is absorbed in the solution, its formula is shown by Equation 1. The absorbance represents the amount of light absorbed by each solution, this was found using Equation 2.

Compared to TiO2, Figure 26a and 26b, which represent the XRD for titania film, it is observed that the crystallinity increases with temperature, which is the same behavior as with zinc oxide films. Furthermore, there is great difference between the samples with SiO2 layer and those without barrier layer. In the samples without barrier layer, sodium diffusion inhibit crystals growing in the film [7].

The percent transmittance was measured using the Spec 20 and the absorbance calculated using equation 2. The results were tabulated.

Afterwards, do the same test again and determine the consistence and observe the soil structure. Questions Considering the samples analyzed, the relationship between texture and consistence varies directly because larger particles may affect the texture to the point where it is rough and the opposite when the
