What we have learnt

  • Kinetic theory provides a molecular perspective on gas behavior, linking pressure, temperature, and volume.
  • The average kinetic energy of gas molecules is directly proportional to temperature, offering insights into thermodynamic properties.
  • The law of equipartition of energy states that energy is equally distributed among degrees of freedom, impacting specific heat capacities of gases.

Key Concepts

-- Kinetic Theory
A theory that explains the behavior of gases in terms of particles in motion, focusing on molecular interactions and energy distribution.
-- Ideal Gas Law
An equation relating the pressure, volume, and temperature of an ideal gas, given by PV = nRT.
-- Mean Free Path
The average distance a molecule travels between successful collisions with other molecules.
-- Law of Equipartition of Energy
A principle stating that energy is shared equally among all accessible degrees of freedom, with each contributing ½ kBT.
