To determine which objects will sink in freshwater (density = 1.0 g/cm³), we need to compare the densities of the objects to that of freshwater.
- An object will sink in water if its density is greater than that of water (1.0 g/cm³).
- An object will float if its density is less than or equal to the density of water.
Here are the densities of the objects:
- Object 1: 0.08 g/cm³ (floats)
- Object 2: 1.9 g/cm³ (sinks)
- Object 3: 0.06 g/cm³ (floats)
- Object 4: 0.03 g/cm³ (floats)
From the analysis:
- Object 1, Object 3, and Object 4 will float because their densities are less than 1.0 g/cm³.
- Object 2 will sink because its density (1.9 g/cm³) is greater than 1.0 g/cm³.
Therefore, Object 2 will sink in freshwater.
