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.

(N/A) No,the amount of salt and sugar that can be dissolved in water at a given temperature is not the same. Solubility is a characteristic property of a substance and varies depending on the nature of the solute.
$(b)$ If she cools the contents of the beakers,crystals of salt and sugar will appear. This happens because the solubility of a solid in a liquid generally decreases as the temperature decreases. As the solution cools,it becomes supersaturated,causing the excess solute to precipitate out in the form of crystals.
