Question

Use the measurements in Table 1 - Measurements of Object A'. to identify the density of object A. Then use the density of object A and Table 'Table 2 common Densities' to identify what object A could be made out of.

A) Density of object A: 2.5 g/cm³, Material: Steel
B) Density of object A: 0.9 g/cm³, Material: Cork
C) Density of object A: 8.0 g/cm³, Material: Gold
D) Density of object A: 1.2 g/cm³, Material: Aluminum

Answer 1

The density of object A at 2.5 g/cm³ suggests it could be made of steel, matching the density values for steel and discounting other materials like cork, aluminum, or gold.

Step-by-step explanation:

To determine the density of object A, we look at its mass relative to its volume. Density is the ratio of mass to volume, with common units being grams per cubic centimeter (g/cm³). Using Table 1, if the density of object A is given as 2.5 g/cm³, for instance, this density is too high for materials such as cork (0.9 g/cm³) or aluminum (1.2 g/cm³), but too low for gold, which has a much higher density of 19.3 g/cm³. Given the options provided, a material such as steel, which has a density closer to 2.5 g/cm³, would be a suitable match for object A. Thus, option A) Density of object A: 2.5 g/cm³, Material: Steel is the appropriate choice.
