Chapter 5, Problem 124AP

Interpretation Introduction

Interpretation:

The change in internal energy ($\Delta U$) for the given process is to be calculated.

Concept introduction:

The change in the enthalpy for any process can be determined using the equation given below:

$\Delta H=\Delta U+P\Delta V$

Here, $\Delta H$ is the enthalpy change, $\Delta U$ is the change in internal energy, and P is the pressure.

The relation between litre atmosphere and joule is represented as

$1\text{ L}\text{.atm}=101.3\text{ J}$

Conversion factor is $\frac{\text{101}\text{.3 J}}{1\text{ L}\text{.atm}}$.

The relation between joule and kilojoule is

$1\text{ J}=0.001\text{ kJ}$

Conversion factor is $\frac{\text{0}\text{.001 kJ}}{1\text{J }}$.
