Much like its household namesake, a molecular sieve utilizes differences in what property of substances to separate the components of mixtures?
A
freezing point

B
particle size

C
solubility

D
density

Let's begin by explaining that a molecular sieve is a device, whose composition allows the absorbtion of molecules that are small enough to pass through its pores, since it is made up of small pores of a precise and uniform size.

Thus, very small molecules manage to pass through the pores of the sieve, while large ones do not.

So, based on this premise, a molecular sieve separates the substances by their size.

Hence, the correct option is B.
