Chapter 12, Problem 12C.1ST

Interpretation Introduction

Interpretation:

With the account of contributions from translation and rotation, the molar internal energy of a gas of diatomic molecules has to be calculated.

Concept Introduction:

Molar internal energy:

Internal energy is the total energy of a system that is necessary to create or prepare the system in any given state. Its common symbol is $\text{U}$. Its unit is $\text{J}$. The molar internal energy refers to the internal energy of one mole of any substance with the unit $\text{J/mol}$. It is represented by the symbol ${\text{U}}_{\text{m}}$.
