Question

Water has maximum density at _________.

Answer 1

• Water has an unusual physical property i.e. anomalous expansion of water.
• When water gets cooled, it first contracts in volume, as do other liquids, but below 4^oC, it starts expanding and continues to do so till the temperature reaches 0^oC, the point at which it freezes into ice.
• At 4^oC, water has its maximum density, 1g/cm³ or 1000kg/m³, and minimum volume.

Water has its maximum density at 4^oC.
