Gas Phase

A gas is a state of matter characterized by particles moving freely with high kinetic energy, filling any container they occupy. Unlike solids and liquids, gases have no fixed shape or volume.

In gases, particles have weak intermolecular forces and move rapidly in random directions, which gives them their ability to expand and compress easily.

Molecular Behavior

Gases exhibit distinct molecular characteristics:

  • Random motion
  • High kinetic energy
  • Large spacing between particles

Properties of Gases

Key characteristics that define gases include:

  • No fixed shape or volume
  • Highly compressible
  • Flow easily
