Question

A student placed several blocks in an aquarium containing water.
What can be concluded about the density of the blocks?
A. Block A is more dense than water
B. Block B is more dense than Block A
C. Block C is less dense than Block A
D. Block D is less dense than water

Answer 1

To draw conclusions about the density of the blocks based on their placement in water, we can use the principle that an object will float if it is less dense than the fluid, and sink if it is more dense.

- If a block floats, it has a density less than that of water (approximately 1 g/cm³).
- If a block sinks, it has a density greater than that of water.

Without specific information about how each block behaves in the water (i.e., whether they float or sink), we cannot definitively determine the relationships of their densities to one another or to that of water.

However, if you specify which blocks float or sink, we could logically determine relationships between their densities. For example:
- If Block A floats, it is less dense than water.
- If Block B sinks, it is more dense than water.
- If Block C floats and Block A floats, but Block C floats higher, then Block C is less dense than Block A.

Thus, without additional context regarding the behavior of each block in the aquarium, it's impossible to conclude which statements are true. Please provide more details about how each block acted in the water.
