Characteristics of Gases
• Physical properties of gases are all similar.
• Composed mainly of nonmetallic elements with
simple formulas and low molar masses.
• Unlike liquids and solids, gases
expand to fill their containers.
are highly compressible.
have extremely low densities.
• Two or more gases form a homogeneous mixture.
