To rank the substances from least dense to most dense, you would list them as follows:
1. Styrofoam
2. Wood
3. Brick
When you click on these substances in that order in the simulation, you may notice that the least dense substance (styrofoam) floats on top of the others, while the most dense (brick) sinks to the bottom. This observation illustrates the principle that an object will float in a fluid if it is less dense than the fluid, and will sink if it is more dense.
For question 4, when you change the substance to water, you can infer its relative density based on the substances you've ranked. Water has a density of approximately 1 g/cm³. Between the substances in your ranking:
- Styrofoam is less dense than water and would float.
- Wood generally has a density ranging from about 0.3 to 0.9 g/cm³, which also suggests it may float, depending on the specific type of wood.
- Brick has a density significantly greater than that of water (usually around 1.6 to 2.0 g/cm³), meaning it would sink in water.
Based on these observations, you could hypothesize that water would fit into your rankings as being more dense than styrofoam and wood but less dense than brick. Thus, a corrected ranking including water might look like this:
1. Styrofoam
2. Wood
3. Water
4. Brick
This conclusion can be justified because of the buoyancy behaviors observed when interacting with a liquid medium in the simulation—since lighter materials float while denser ones sink.
