How are heterogeneous and homogeneous mixtures separated?

Explanation:

Homogeneous mixture is separated using two stage separation process: mobile stage and stationary stage. The mobile phase are absorbent such as water, chemicals while the stationary stage is the column used for the separation process. The integral method of separation of homogeneous mixtures is called chromatography (analytical or preparative). Other method of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture.

While heterogeneous mixtures are separated based the properties of the components. One method of separation of solids suspended in liquids is simple filtration.

b is the correct answer

mark me brainliest and hope this

the dependant variable is spilled water

the independent is the heat
