Key Syllabus Coverage (Official IGNOU Curriculum)

• Block-1: Kinetic Theory of Gases
  • Fundamental principles of kinetic theory: molecular motion, pressure, and temperature.
  • Derivation of the ideal gas law from kinetic theory assumptions.
  • Applications: Maxwell-Boltzmann distribution, mean free path, and viscosity of gases.
• Block-2: The Zeroth and First Laws of Thermodynamics
  • Zeroth Law: Thermal equilibrium and temperature as a state function.
  • First Law: Conservation of energy in thermodynamic systems (work, heat, internal energy).
  • Adiabatic processes, isothermal expansion, and thermodynamic cycles.
• Block-3: Second and Third Laws of Thermodynamics
