Question

The temperature of water at the surface of a deep lake is $2^0$ C. The temperature expected at the bottom is

• A. $0^0$ C
• B. $2^0$ C
• C. $4^0$ C
• D. $6^0$ C

Answer 1

The correct option is C $4^0$ C

It is supposed that at the deepest point density is maximum. But density is maximum at $4^{o}C$. Hence, temperature at bottom is $4^{o}C$
