Question

solid water floats on liquid water. why does this happen? ice is less dense than water vapor ice is less dense than liquid water

Explanation:

To determine why solid water (ice) floats on liquid water, we analyze the density concept. An object floats on a liquid when its density is less than the liquid's density. The first option compares ice's density to water vapor (a gas), which is not relevant here as we're dealing with liquid water. The second option states ice is less dense than liquid water, which explains why ice (solid water) floats on liquid water, as substances with lower density float on those with higher density.

Answer:

B. Ice is less dense than liquid water
