Final answer:
The materials listed will arrange themselves from highest to lowest density: Mercury, Lead, Water, Wax, Wood, Oil, and Gas, based on the densities given.
Step-by-step explanation:
In answering the student's question of arranging materials of different densities in a container, we consider the densities provided:
- Liquids: Mercury (13.5 g/cm³), Water (1.0 g/cm³), Oil (0.89 g/mL)
- Gas: Gas (0.081 g/cm³)
- Solids: Lead (11.34 g/cm³), Wood (0.51 g/cm³), Wax (0.87 g/cm³)
When these materials are placed in the same container, they would arrange themselves according to their densities, from highest to lowest, as follows:
- Mercury
- Lead
- Water
- Wax
- Wood
- Oil
- Gas
This arrangement is based on the principle that denser materials sink to the bottom while less dense materials float atop one another.
