Question

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

• A. $2^{\circ }C$
• B. $3^{\circ }C$
• C. $4^{\circ }C$
• D. $1^{\circ }C$

Answer 1

The correct option is C $4^{\circ }C$

The densest layer of water will be at bottom. The density of water is maximum at 4∘C. So the temperature of bottom of lake will be 4∘C.

option C is correct.
