Because the atoms or molecules in a gas are several orders of magnitude further apart than they are in a liquid or solid.
Temperature in this instance will not affect density, but rather pressure. The density of the gas will be much smaller than the density of a liquid or solid of the same chemical because it is a gas. The formula for density is mass over volume, and a gas has no measurable mass, making the gas always less dense than the liquid and the solid.
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
Sublimation - the process by which a substance goes directly from the solid to the gaseous state without passing through the liquid state.
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
That depends on the liquid and the solid. Liquid mercury has a very high density. Liquid gasoline has a very low density. At the melting point the density of a liquid and a solid are almost the same.
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form

Vapour
Vapour
when a substance exists as a liquid or solid under ordinary conditions its gaseous phase is called a vapor
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent.
The process of transforming a substance from a solid state to a liquid state is celled melting. The process of transforming a substance from a liquid state into a gaseous state is called vaporization.
When a substance changes from a solid to a liquid and vice versa, its density changes.
by hitting your self in the head
If a substance that exists in liquid state was not in liquid state then it was in its other states of matter namely solid, gaseous.
The solid cannot float in this liquid.
