Explain the following:
Fishes survive in ponds even when the atmospheric temperature is below `0^(@)C`.

Explain the following statement: "Fishes survive in ponds even when the atmospheric temperature is well below 0^@C ".

Most substances contract on freezing . However, water does not belong to this category. We know that water expands on freezing. Further , coefficient of volume expansion of water in the temperature range from 0^(@)C to 4^(@)C is negative and above 4^(@)C it is positive . This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it is still above 4^(@)C . If the atmospheric temperature is below 0^(@)C
