Gas in physics is a form of matter, such
as air, in which molecules move randomly in
otherwise empty space, filling any size or
shape of container into which the gas is put.
A 1cm cube of of air at room temperature
contains 30 trillion molecules moving at
an average speed of 500 metres per second
(1,800 kph/1,200 mph). Gases can be
liquefied by cooling, which lowers the speed
of the molecules and enables attractive
forces between them to bind them together.
