In a 10 m deep lake, the bottom is at a constant temperature of `4^(@)C`. The air temperature is constant at `- 4^(@)C. K_(ice) = 3 K_(omega)`. Neglecting the expansion of water on freezing, the maximum thickness of ice will be

A

`7.5m`

B

`6m`

C

`6m`

D

`2.5m`

Text Solution

Verified by Experts

(a) `KA((4-0)/(10-x))=3KA((0-(-4))/x)`

`implies x=7.5m`
