Chapter 4, Problem 4B.16E

Interpretation Introduction

Interpretation:

The contribution of motion to the molar internal energy of ${\text{N}}_2\left(\text{g}\right)$ at $25°\text{C}$ has to be estimated.

Concept Introduction:

The energy of a molecule due to its motion in the three dimensional space is referred to as the translational energy.  The energy of a molecule due to its rotational motion in the three dimensional space is referred to as the rotational energy.  The total molar internal energy of a molecule at temperature $T$ is the sum of the contribution of translational and rotational kinetic energy.
