The water on the surface of a lake is just about to freeze. The most likely temperature at the bottom of the lake is
$4^{\circ} \mathrm{C}$
$0^{\circ} \mathrm{C}$
$-4^{\circ} \mathrm{C}$
$-273^{\circ} \mathrm{C}$
Solution
The water at the bottom of the lake will have maximum density. The density of water is maximum at $4^{\circ} \mathrm{C}$. Hence, the temperature at the bottom of the lake is $4^{\circ} \mathrm{C}$
