Planet Puzzle The Planet Puzzle Abstract: To identify the composition of thirteen objects By measuring the mass and volume of thirteen objects and plotting on a graph the four slopes of the lines you can determine the four compositions. It was determined that the composition of the objects were Lucite, Magnesium, Brass, and Aluminum. Procedure: The procedure is as written. Data and Results: Part I ' Part II Exploration ' Part III Concept Extension ' Graphs: See attached graph Sample Calculations: Volume: Volume of Object 13 V sample = V final - V initial Vs = 23.8mL - 23.01mL Vs = 0.8mL Density: Density of Object 13 D = Mass/Volume D = 10.701g/0.8mL D = 13g/mL Questions: 1. The four volumes of the blocks are, 0.8mL, 3.2mL, 5.8mL, 10.2mL. 2. No it is not suitable for calculating the smallest block. 3. A better way to obtain a more accurate estimate of the volume for the smallest block would be to use the water displacement theory. 4.a) Using intensive properties will be more useful because intensive properties are exclusive to certain elements and are independent of the amount of the sample you have. 4.b) Color, mass, and temperature are extensive properties because they depend on the amount of the sample present and can be change by physical means. Hardness and density are intensive properties sample, because, objects, mass, properties, materials, four, intensive, density, amount, volume, property, line, samples, independent, y2, y1, x2, x1, thirteen, object, means, lines, extensive, composition, aluminum, 9a, slope, using, reason, present, planets, part
