Chapter 2, Problem 2.25CP

Interpretation Introduction

Interpretation:

The reason for $C_{P,m}$ to be not a function of argon but a function for ethane within the temperature range needs to be explained where excitation of electron does not take place

Concept Introduction :

Heat capacity in thermodynamics is the amount of energy required to alter the material’s temperature by the provided amount. Heat capacity is the property which is dependent on material property. Below relation is used to define the relation of heat capacity:

  $C=\frac{dq}{dt}$

Here, $dq$ is change in heat and $dt$ is change in time.

Electron excitation is the transference of a bounded electron to a more energetic, but still bounded state.
