Fish does not always grow in warm water so well as in cold water. Why ?

What is Cryoscopic constant?

Why is freezing point depression of $0.1 \mathrm{M}$ sodium chloride solution nearly twice that of $0.1 \mathrm{M}$ glucose solution?

How does anti-freeze work as a freezing depression agent?

Discuss how the solubility of the solids in liquids is affected by temperature.

What is Ebullioscopic constant?

Determine the amount of $\mathrm{KCl}$ which must be added to $1 \mathrm{Kg}$ of water so that the freezing point is depressed by $2 \mathrm{K}$. (${\mathrm{K}}_{\mathrm{f}}$ for water $=1.86 \mathrm{K} \mathrm{Kg} {\mathrm{mol}}^{-1}$)
