Ronald makes his own chicken broth. He uses the tool shown below to separate the broth from the fat.

Question

Why does this tool work to separate the mixture?

The broth has a lower boiling point than the fat.
The broth has a higher density than the fat.
The broth has larger particles than the fat.
The broth has a higher melting point than the fat.

Answer 1

The correct answer to why the tool works to separate the broth from the fat is:

The broth has a higher density than the fat.

This principle allows the broth, which is denser, to be separated from the fat, which is less dense, typically floating on top. This separation method takes advantage of the differences in density between the two substances.
