Question
How does addition of heat to a system at different temperatures changes disorder or $\Delta S$ ?

Answer

  • The amount of heat added to a system at higher temperature causes less disorder than when the heat is added at lower temperature.
  • Since disorder depends on the temperature at which heat is added, ΔS relates reciprocally to temperature.
  • This can also be explained from equation,
    $\Delta S =\frac{Q_{ rev }}{T}$
