Ice floats because:

Correct answer: A. It is less dense than water

  • A. It is less dense than water
  • B. It is more dense than water
  • C. It occupies less space than water
  • D. It occupies more space than water

Explanation

Therefore, the correct statement for why ice floats is A becuase water has a unique property, as it expands when temperature falls below 4°C. Water is most heavy at 4°C, therefore ice (solid water) is less dense then liquid water and this is that ice float is liquid water.
