To determine which material would end up on the bottom if all of these substances were placed together in the same container, we need to understand the concept of density. Density is defined as mass per unit volume, commonly measured in grams per cubic centimeter (g/cm³). The substance with the highest density will sink and end up at the bottom, while the substance with the lowest density will float on top.
Let's review the densities of the given materials:
- Aluminum: 2.7 g/cm³
- Benzene: 0.9 g/cm³
- Magnesium: 1.7 g/cm³
- Water: 1.0 g/cm³
- Iron: 7.8 g/cm³
To identify which material will end up on the bottom, we need to find the material with the highest density.
1. Compare the density of Aluminum (2.7 g/cm³) with the other materials.
2. Compare the density of Benzene (0.9 g/cm³) with the other materials.
3. Compare the density of Magnesium (1.7 g/cm³) with the other materials.
4. Compare the density of Water (1.0 g/cm³) with the other materials.
5. Compare the density of Iron (7.8 g/cm³) with the other materials.
Through comparison:
- Iron has the highest density of 7.8 g/cm³.
- The densities of Aluminum (2.7 g/cm³), Benzene (0.9 g/cm³), Magnesium (1.7 g/cm³), and Water (1.0 g/cm³) are all lower than Iron's density.
Therefore, the material that would end up on the bottom is the one with the highest density, which is Iron.
So, the answer is:
Iron.
