Question

An ice sheet 5m thick covers a lake that is 20m deep. what is the temperature of the water at the bottom of the lake? explain your answer . coefficient of volume expansivity at 20 degree centigrade is 2.1x10^-4​

Answer 1

Answer:

4°C

Explanation:

An ice sheet 5m thick covers a lake that is 20m deep. The temperature of the water at the bottom of the lake is 4°C because it is dense, making it easy to sink.

Coefficient of volume expansivity at 20 degree centigrade is 2.1x10^-4​.

Answer 2

Answer:

4°C

Explanation:

Water is densest at 4°C.  Since dense water sinks, the bottom of the lake will be 4°C.
