Condensation is the conversion of gas to liquid by cooling. Individually and together they can be used for the separation of mixtures. Distillation is the process of separating a liquid from the solution of a soluble solid. The solution is heated in a flask and passed through a condenser. The pure liquid is collected in a beaker.

The process in which solids are separated from the liquid is known as sedimentation as all of the solids sink to the bottom of the beaker and leave a clear layer of liquid on top. It is purely based on the principle that heavier particles in a solution settle down at the bottom of the container in which the mixture is contained.

A mixture contains three different substances X, Y and Z. They are of the same size, cubical in shape and yellow in colour. X particles are very heavy, insoluble, non-magnetic and contribute 50% of the mixture. Y particles are very light, insoluble, non-magnetic and contribute 40% of the mixture. And Z particles are iron pieces.
