Question

why does ice float? ice is more dense than liquid wate♣ ice is less dense than liquid water. ice has more surface tension. none of the above

Explanation:

To determine why ice floats, we use the principle of buoyancy: an object floats in a fluid if its density is less than the fluid's density. Ice is a solid form of water. The molecular structure of ice (due to hydrogen bonding) creates a lattice with more space between molecules compared to liquid water, making ice less dense than liquid water.

• The first option is incorrect because if ice were more dense, it would sink.
• The third option is incorrect because surface tension relates to the cohesive forces at the surface of a liquid, not why ice floats (which is about density).

So the correct reason is that ice is less dense than liquid water.

Answer:

B. Ice is less dense than liquid water.
