Explanation:
1: Mixtures can be either homogeneous or heterogeneous. A mixture in which its constituents are distributed uniformly is called homogeneous mixture, such as salt in water. A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water.
2: Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.
3: Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. ... Evaporation and condensation happen when these molecules gain or lose energy. This energy exists in the form of heat.
4: By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. ... Oil and water do not mix, instead forming two distinct layers called phases.
