GENERAL CHARACTERISTICS OF GASES
Gases have limitless expansibility. They expand to fill the
entire vessel they are placed in.
Gases are easily compressed by application of pressure to a
movable piston fitted in the container.
Gases can diffuse rapidly through each other to form a homogeneous mixture.
Gases exert pressure on the walls of the container in all directions.
When a gas, confined in a vessel is heated, its pressure increases. Upon heating in a vessel
fitted with a piston, volume of the gas increases.
The above properties of gases can be easily explained by the Kinetic Molecular Theory which
will be considered later in the chapter.
