Gases are identified as materials that

  • have no definite shape
  • have no definite volume
  • can be easily compressed
  • can flow

In a gas the particles move in all directions and the bounce off one another, causing the particles to spread out further and further.

If the gas is held in a container the particles will bounce off the walls of the container as well as each other.

Water vapour is an example of a gas. Water vapour usually is invisible.
