Thermodynamics - Index

Follow the links below to explore some basic concepts of Thermodynamics:

• • What is Thermodynamics?
  • Thermodynamic system
  • Thermodynamic variables
  • Thermodynamic processes. PV diagram
  • Equation of state of an ideal gas – Isotherms of an ideal gas
  • Temperature, thermometer and temperature scales
  • First Law of Thermodynamics
    • Heat – The mechanical equivalent of heat
    • Work done by a gas
    • Internal energy. Internal energy of an ideal gas
    • Mayer’s relation (Mayer’s law)
    • Reversible processes of an ideal gas
      • Isothermal process
      • Isochoric process
      • Isobaric process
      • Adiabatic process
      • Thermodynamic cycle
  • Second law of thermodynamics. Entropy
    • Calculation of the entropy change in reversible processes
  • Heat engine. Kelvin–Planck statement of the second law of thermodynamics
    • Carnot heat engine
  • Heat pump, Clausius statement of the second law of Thermodynamics
    • Carnot heat pump (or Carnot refrigerator)
  • Entropy variation of an isolated system. Entropy of the universe
  • Thermodynamics problems and solutions
    • Calculation of the work done by an ideal gas
    • Application of the First Law of Thermodynamics
    • Reversible cycle with an adiabatic process (ideal gas)
    • Theoretical Diesel cycle
