Question

Sort the states of water by density, from the least dense to the most dense.

Answer 1

You didn't supply the different states, but we'll assume they are solid (ice), liquid and gas (vapor).

You know that ice floats on top of liquid water, so it must be LESS DENSE than liquid. And a gas has a lower density than a liquid or a solid because its volume can expand to occupy the full container. Since density is defined as mass/volume, for a gas the volume can be large, making the density low.

Least dense to most dense: gaseous water < solid water (ice) < liquid water
