Vedclass · Answer

(C) lake cools from the surface down. Above $4^{\circ}C$,the cooled water at the surface flows to the bottom because of its greater density.However,when the surface temperature drops below $4^{\circ}C$ (in this case,$2^{\circ}C$),the water near the surface becomes less dense than the warmer water below.Consequently,the downward flow ceases,and the water at the bottom remains at $4^{\circ}C$ until nearly the entire lake is frozen.

The surface of the lake is at $2^{\circ}C$. Find the temperature of the bottom of the lake in $^{\circ}C$.
