Answer 1

When the temperature of water decreases below 4 °C it’s volume increases.

The unusual expansion of water is unique. Water has greatest density and minimum volume at 4 °C. At temperatures below 4 °C, water expands, increasing its volume. Ice floats because it is less thick than liquid water.
