When water is heated from 0^(@)C to 10^(@)C , its volume

Which of the following behaves like water between 0^(@)Cand4^(@)C .

Expand the following Sin(A + B+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^(0)C to 4^(0)C is negative and above 4^(0)C it is positive. This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it has an extremely important effect on plant and animal life in lakes. As the atmospheric temperature goes down. but it is still above 4^(0)C :
