Answer 2

Answer:

gases

Explanation:

The three common phases (or states) of matter are gases, liquids, and solids. Gases have the lowest density of the three, are highly compressible, and completely fill any container in which they are placed.Notice that the solid (steel) is the most dense, the gas (air) is the least dense, and the density of the liquid (water) is in between.Hydrogen

The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.
