Chapter 16, Problem 16A.5BE

Interpretation Introduction

Interpretation:

The flux of energy that arises from a temperature gradient of $8.5\text{K}{\text{m}}^{-1}$ in a sample of ${\text{N}}_{\text{2}}$ is to be calculated.

Concept introduction:

Energy flux is described as the quantity which measures the rate of energy transfer through unit area surface.  The flux of energy arising from a temperature gradient is calculated by the formula shown below.

    $J=-\kappa \frac{\text{d}T}{\text{d}z}$
