Final answer:
A saturated solution is a solution that contains the maximum amount of solute that can be dissolved at a given temperature. A pure substance is a substance that is made up of only one type of particle. A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid or gas but will settle out over time.
Step-by-step explanation:
A saturated solution is a solution that contains the maximum amount of solute that can be dissolved at a given temperature. If more solute is added, it will not dissolve and will settle at the bottom. An example is adding salt to water until no more salt can dissolve.
A pure substance is a substance that is made up of only one type of particle. It has a uniform composition and properties throughout. An example is pure water, which consists of only water molecules.
A suspension is a heterogeneous mixture where solid particles are dispersed in a liquid or gas but will settle out over time. An example is a mixture of sand and water, where the sand particles can be seen and will settle at the bottom over time.
