There are two layers of water in a calorimeter, the lower one colder at temperature 30^(@)C and the upper one hotter at temperature 60^(@)C . The mass of lower water is m and volume is V . The mass of upper water is 2 m and volume is 2V . The coefficient of volume expansion for water is gamma . When the temperature of the whole system becomes equal , the ratio of new volume to the old volume is .

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 . As the atmospheric temperature goes below 4^(@)C
