ideal gas equation

• What does the kinetic theory of gases describe?

  The constant motion of gas particles
• What is one assumption of the kinetic theory regarding gas particle movement?

  Gas particles move rapidly and randomly
• What type of collisions occur between gas particles according to the kinetic theory?

  Collisions are elastic - no energy is lost
• What does the average kinetic energy of gas particles depend on?

  It depends only on their temperature
• What is a hypothetical gas that obeys all kinetic theory assumptions called?

  Ideal gas
• How do real gases differ from ideal gases?

  Real gases have intermolecular attractions and volumes
• Which types of gases come close to ideal behavior?

  Noble gases like helium and neon
• What is the ideal gas equation?

  pV = nRT
• What do the variables in the ideal gas equation represent?

  Pressure, volume, moles, gas constant, temperature
