Measurement And Density Essay Example

standard density with its calculated density.

The density of calculated (in g/cm3) for Experiment-2 can be measured for various colored cubes using Vernier Calipers and Digital Weighing balance. The weights for each cube (Red,

Green, and Blue) can be measured using the balance. The results are recorded in a table with columns for the cube number (1-5) and the average mass. © KC Distance Learning.

The Vernier Caliper was used to measure the length (L), width (W), and height (H) of Red, Green, and Blue cubes. The average volumes of the Red and Green cubes were calculated, along with their masses and densities (mass/volume). The presence of Iron, Copper, and Zinc in each cube was identified. It should be noted that standard density values for these elements are: Iron - 7.86 g/cm3, Copper - 8.96 g/cm3, Zinc - 7.13 g/cm3.

The lab data needs to be analyzed, including the calculations used to determine the calculated densities. Additionally, the percent error should be calculated and experiment 1 and experiment 2 results should be compared. Once the experiment is complete, a conclusion must be provided which explains any problems or answers raised by the lab's purpose. It is important to determine if the hypothesis is supported by gathered data and use it as evidence for your answer. Finally, evaluate if there are other explanations that could explain your conclusion.

Answer the post lab questions provided by KC Distance Learning before submitting your report to your teacher. Make sure to present all calculations wherever required. For reference purposes, use the following table that displays the density of different substances, including Aluminum, Oak, Pine, Polypropylene, PVC, Steel, Water, Lead and Bismuth, in grams per cubic centimeter (g/cm3):

Should the density of a damaged metal object shaped like a cube be determined by measuring only one side and cubing it, without any further data? Explain your reasoning.

2. If the density of a cube is determined to be 1.40 g/cm3, would it differ if another cube made of the same material has twice its mass? Explain.
3. A cube with a mass of 0.

Identify the object with a volume of 20.0 cm3 and weighing 0084 kilograms, using the density table provided. Make sure to convert, if necessary. 4.

Based on the density of lead in the table provided, what is the mass of a lead cube with 7.00 centimeter sides? © KC Distance Learning 5.

When you add a piece of aluminum weighing 15.00 grams to a graduated cylinder filled with 50.00 milliliters of water, the water level will increase.

After dropping the aluminum, what would be the new volume of the graduated cylinder? Also, how many substances from the density table provided would float in water?
