Measurement of Quantities

Procedure: To even dispirit the lab, we (group) gathered the materials needed to do the experiment (list of materials higher up). To start the experiment, we took our closeness ingests and put them on the triplex beam balance to let on the mass of the niggardness consumes. and indeed we preserve the data we found to the nearest 0.001 gram. We also fipple flute the un surety for every measurement we took in the experiment. For our contiguous pay back of measurements, we used a graduated piston chamber to measure the people of the samples by using water displacement, which is where you start with a certain number of mL of water and accordingly place the sample into the water and record the difference of the new-fangled number from the head start number of mL, and then recorded the measurement to the nearest 0.5 mL. We then metrical the dumbness of the samples by using the aspect for density (Density is equal to the mass of a sample divided by its i ntensiveness) then recorded it as g/mL. Then we started on Method B. Method B of the measurements prompted the group to find the volume of the samples using a vernier scale scale caliper.

This was not applicable to the foreign rock because of its dimensions. Continuing, we mensural the diameter and height of the samples using the vernier caliper and arrangement those values to the nearest .05 cm. We then measured the volume of the samples by using the formula V=?r^2 h. The density we calculated again with the same formula as above and we then moved on to purpose the percent faulting of both the alum inum and hog samples densities. For calcul! ated the percent error of the densities we had to first find the actual densities of copper and aluminum. Then, we used this formula to find the percent error.If you want to produce a full essay, order it on our website: OrderCustomPaper.com
