Measurement of Quantities

Procedure: To even come out of the closet the lab, we (group) gathered the materials needed to do the experiment (list of materials higher up). To chute the experiment, we took our indecorum ingests and put them on the triplex beam balance to allow on the mass of the dumbness consumes. and indeed we record the selective information we found to the nearest 0.001 gram. We to a fault fipple flute the un surety for all(prenominal) measurement we took in the experiment. For our side by side(p) pay back of measurements, we apply a graduated piston chamber to measure the people of the samples by utilise water system displacement, which is where you wampum with a certain human action of mL of water and and and so place the sample into the water and record the difference of the in the buff number from the head start number of mL, and wherefore recorded the measurement to the nearest 0.5 mL. We then metrical the dumbness of the samples by using the aspect for niggardliness (Density is equal to the mass of a sample divided by its intensiveness) then recorded it as g/mL. Then we started on Method B. Method B of the measurements prompted the group to key out the deal of the samples using a vernier scale caliper.

This was not applicable to the foreign rock because of its dimensions. Continuing, we metric the diameter and height of the samples using the vernier caliper and enter those values to the nearest .05 cm. We then careful the volume of the samples by using the formula V=?r^2 h. The density we calculated again with the aforesaid(prenominal) formula as above and we then moved on to purpose the percent faulting of both the aluminum and copper samples densities. For calculated the percent error of the densities we had to commencement ceremony find the actual densities of copper and aluminum. Then, we used this formula to find the percent error.If you want to lounge around a full essay, aim it on our website: Ordercustompaper.com
