The molecules are farther apart in a gas.
the exosphere, which is the highest layer of Earth's various layers of the atmosphere. it is the least dense because it is so high up the molecules are spread apart a lot.Type your answer here...
Oil will sink in water, so is the least dense.
Water vapor is the least dense form of water, and the molecules are farthest apart from each other. Liquid water is the densest form of water. In ice, molecules form a crystal lattice.
The farther away from the Earth's surface, the less dense the air will be. Of course, once you break out of the atmosphere, there will be no air around you.

The least dense type of water is ice because when water freezes, its molecules arrange themselves in a hexagonal structure that increases the volume of the substance compared to liquid water. This expansion causes ice to be less dense than liquid water, which is why ice floats on water.
Of the 3 more common phases of matter, solid, liquid and gas, gas is always the least dense because the particles are not as close together.
No. In fact it is the most dense planet. The least dense is Saturn.
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
Helium is the least dense element at normal conditions.
'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.
