Answer 1

Answer:

Normally, liquids become increasingly dense as they are cooled down, but water reaches a maximum density at about 4 degrees Celsius (39.2 Fahrenheit). Below this point it is less dense, so when it freezes and becomes ice at 0 degrees Celsius (32 Fahrenheit), the ice is less dense than the water.
