Chapter 2.5, Problem 8E

Interpretation Introduction

Interpretation:

The change in internal energy and the change in enthalpy.

Concept Introduction:

The expression of change in internal energy $\left(d\underset{\_}{U}\right)$.

$d\underset{\_}{U}=C_V^{*}\left(dT\right)$

Here, constant volume is $C_V^{*}$, and change in temperature is $dT$.

The expression to obtain the value of $C_V^{*}$.

$C_V^{*}=C_P^{*}-R$

Here, constant pressure heat capacity for ideal gas is $C_P^{*}$ and gas constant is R.

The expression to obtain the change in enthalpy $\left(d\underset{\_}{H}\right)$.

$d\underset{\_}{H}=C_P^{*}dT$
