Give an example each for the mixture having the following characteristics. Suggest a suitable method to separate the components of these mixtures:
$(a)$ $A$ volatile and a non-volatile component.
$(b)$ Two volatile components with appreciable difference in boiling points.
$(c)$ Two immiscible liquids.
$(d)$ One of the components changes directly from solid to gaseous state.
$(e)$ Two or more coloured constituents soluble in some solvent.

Sidak took $50\, mL$ of water in two beakers at room temperature and added sodium chloride to one beaker while sugar to the other,until no more solute could be dissolved. Then she heated the contents of the beakers and added more solutes in them.
$(a)$ Will the amount of salt and sugar that can be dissolved in water at a given temperature be the same?
$(b)$ What would you expect to happen if she cools the contents of the beakers? Justify your answer.

What is the effect of temperature on the solubility of solids in liquids?
