Chapter 2, Problem 2C.1BE

Interpretation Introduction

Interpretation: The values of $q\text{, }w\text{, }\Delta H$ and $\Delta U$ have to be calculated when $1.7{\text{5 mol C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}\left(\text{l}\right)$ is vaporized at $\text{260 K}$ and $1$ bar.

Concept introduction: The system is said to have gone through a process when the initial state is changed to the final state.  The properties of the system such as temperature, pressure, enthalpy, entropy are changes in thermodynamic process.  Thermodynamics address temperature and heat and their relationship to work, energy and matter.
