(iii) Separation​

Answer 1

Answer:

1.

the action of separating or being separated; a situation or period of being apart

2.

an agreement where a couple decide not to live together any more

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid (gas, solvent, water, ...) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which is fixed a material called the stationary phase.
