The top of a lake is frozen as the atmospheric temperature is `-10^(@)C`. The temperature at the bottom of the lake is most likely to be,

A

`4^(@)C`

B

`0^(@)C`

C

`-4^(@)C`

D

`-10^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A
The temperature of water in contact with ice is `0^(@)C`. The temperature at bottom of lake is most likely to be `4^(@)C` because at this temperature, water is most dense and settles at bottom due to natural convection.
