Answer
A part of sample with uniform composition and properties is a phase. A homogeneous mixture consists of a single phase. A heterogeneous mixture contains of two or more phases.
Work Step by Step
A homogeneous mixture is a mixture that looks alike meaning that it consist same composition. Thus it would be a substance evenly distributed (uniform) and has only one phase.
A heterogeneous mixture is a mixture that looks different meaning that it consists of different compositions, thus it is a solution with two or more substances not evenly distributed (not uniform) and has two or more phase.
