Chapter 4, Problem 4B.3AST

Interpretation Introduction

Interpretation:

The contribution of motion to themolar internal energy of water vapor 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.
