Question

Water contracts on heating between the temperatures

Answer 1

1. Though liquids expand when heated, water contracts between 0°C and 4°C because water has its maximum density at 4°C.
2. Above 4°C, Water expands.
3. The density of water reaches its maximum at 4 degrees Celsius and begins to decrease below this temperature.
4. Because water molecules usually form open crystal structures in solid form, the density decreases as it freezes.
