Question

Ice floats over the surface of water because

• A. its density is less than that of water
• B. its density is more than that of water
• C. its molecules are closely packed and no vacant spaces are there
• D. its molecules are held together by strong forces of attraction

Answer 1

The correct option is A its density is less than that of water

The mass per unit volume of a substance is called density. Due to the presence of large vacant spaces in the structure of ice, the overall volume of ice increases. Therefore, the density of ice is lower than that of water. This allows ice to float on the surface of water.
Hence, the correct answer is option (a).
