Final answer:
B can be separated from C due to their different densities, which allow for their separation using physical methods. Density is an intensive property that remains constant for a substance regardless of the sample size, making it a key characteristic for separation processes.
Step-by-step explanation:
The density of B can be differentiated from the density of C by considering that substances with different densities can be separated physically. In the context given, B can be separated from the mixture in step 2 due to the difference in density, which is an intensive property that does not depend on the size of the sample.
A substance like aluminum has a density of 2.70 g/cm³ at 20°C, regardless of its mass or volume. In mixtures, a homogeneous mixture has a uniform composition throughout and can include solutions like tea in water, while a heterogeneous mixture like orange juice with pulp has a non-uniform composition.
Separation methods such as distillation or crystallization utilize physical properties, like differences in boiling points, to separate components of a mixture.
