The coefficient of thermometric conductivity is defined differently in Landau's and Chandrasekhar's texts. Landau defines it as thermal conductivity divided by density and specific heat at constant pressure, while Chandrasekhar uses the same formula but at constant volume. Both definitions are valid, reflecting different measurement approaches to thermometric conductivity.
PREREQUISITESPhysicists, thermodynamic researchers, and students studying material properties and thermal conductivity measurements.
Sagar_C said:Landau's book defines it as thermal conductivity/density/specific heat at constant pressure while Chandrasekhar's book defines it as thermal conductivity/density/specific heat at constant volume. I am confused. Any comments?
