What happens when a saturated solution is cooled?

Smoke and fog both are aerosols. In what way are they different?

During an experiment, students were asked to prepare a $10\%$ (mass/mass) solution of sugar in water. Ramesh dissolved $10\,g$ of sugar in $100\,g$ of water, while Sarika prepared it by dissolving $10\,g$ of sugar in water to make $100\,g$ of the solution.
$(a)$ Are the two solutions of the same concentration?
$(b)$ Compare the mass percentage of the two solutions.

Which of the following will show the "Tyndall effect"?

Why does a mixture not have a fixed melting or a fixed boiling point?

To make a saturated solution,$36 \,g$ of sodium chloride is dissolved in $100 \,g$ of water at $293 \,K$. Find its concentration at this temperature. (in $,\%$)
