Question
What will be the approximate temperature of water in the lake shown in the following diagram?
(i) At X, and
(ii) At Y?
Solution
The layer at the top level is ice so its temperature is therefore 0°C and temperature at every layer of water below ice increases by 1°C
(i) At X = 1°C since it is the first layer below the ice
(ii) At Y = 4°C since it is the fourth layer below ice
