Vlad Shtefanyuk Year 12, Physics HL ending of Density lab report basis: This experiment is ab emerge determine the niggardliness of several preys gain ground of the same square. Aim: The conception of this experiment is to determine the absorption of six objects of the same material but different treat and dimensions by finding out mass and volume. Apparatus: Balance Ruler vernier scale Calipers Micrometer screw gauge sextette objects of the same material Method: 1. for all(prenominal) ace objects length, breadth and height were careful utilize Vernier Calipers. 2.Each object was weighed using a balance. 3.The diameter and the length of each cylinder shaped object were measured. 4.The attainment errors were calculated and written shine for each object Results: aims 1-4: Length /mm ±0.03 mmWidth /mm ±0.03 mmHeight /mm ±0.03 mmWeight /g ±0.005 g hindquarters 130.3515.003.1511.43 fair game 230.0015.006.0022.56 butt 360.1014.953.0022.61 end 459.8015.006.0045.03 disapproves 5 and 6: Length /mm ±0.003 mmdiameter /mm ±0.03 mmWeight /g ±0.005 g object lens 540.0015.9567.94 Object 659.1018.00116.
58 ledger for objects 1-4 were calculated by multiplying length x width x height Table of volumes for objects 1-4: Volume /mm3Percentage uncertainty Object 11400± 1.0 % Object 22700± 0.8 % Object 32700± 1.0 % Object 45400± 0.8 % Table of volumes for objects 5 and 6: Volume /mm3Percentage uncertainty Object 52000± 0.2 % Object 63300± 0.2 % Graph touch on: As objects 2 and 3 had the same mass and absorption, I drop counted it as one point on the graphical record. . By conniving the gradient of the graph I have obtained the density of the objects: m = 8.33 gcm-3 Conclusion: By calculating the gradient of the graph, I gear up the density of the objects which were tested was 8.33...If you want to pull out a spacious essay, vow it on our website:
