# Coefficient of thermometric conductivity

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?

I think both the books are correct. These are just the different "ways" to measure thermometric conductivity.

Any other views ?
