Q:

Why does gas have lower density than liquids?

A:

Quick Answer

Gas has a lower density than liquids because it is not compressed as tightly as liquids, meaning there are fewer atoms per unit of volume. In a liquid, atoms are free to move but remain closely associated, while in a gas, atoms have lots of free space between one another.

Full Answer

Note that while the densities of both liquids and gases can vary with temperature and pressure, the density of a gas is always considerably lower than that of a liquid. Also, with significant pressure, a gas can be forced to condense into a liquid. One tool that explores the relationship between temperature, pressure and the phase of a substance is a phase diagram.

  • Q:

    What is the order of most dense to least with solids, liquids and gases?

    A:

    Solids are denser than liquids, and liquids are denser than gases at room temperature. Solids are atoms and molecules in a relatively motionless crystal lattice configuration. Liquids are comprised of molecules with more energy and aren't confined to a lattice. Gases are high energy, and their molecules are spaced apart.

    What is air density?

    A:

    Air density is the mass of air per unit of volume it occupies, and it is expressed in kilograms per cubic meter when using the metric system. In the free atmosphere, air density decreases when temperature increases or when the air is humid. However, air density increases when pressure increases.
