Properties of Gases

• What is the kinetic theory of gases?

  Gas molecules are in constant, random motion and their kinetic energy is stored in collisions between gas particles.
• What is the pressure of gases?

  The force exerted per unit area by gas particles colliding with the container walls.
• What is the temperature of gases?

  Average heat energy of particles in a system. An increase in temp. indicates gas particles move more quickly.
• What is the volume of gases.

  Gases occupy their whole container.
• What is a variable volume system?

  Have walls that can adjust to the volume of the gas such as a balloon or a syringe.
• What is a fixed volume system?

  Closed system, the walls don't expand.
• What is Gay-Lussac's Law?

  P1/T1=P2/T2
• What is Charles Law?

  V1/T1=V2/T2
• What is Boyle's Law?

  P1V1=P2V2
• What is SLC?

  298 K, 100kPa
• What is STP?

  273K, 100kPa
