Chapter 2, Problem 2.19P

(a)

Interpretation Introduction

Interpretation:

To determine the enthalpy of Liquid water at $180°\text{C}$ and $1002.7\text{ kPa}$ has an internal energy (on an arbitrary scale) of $762.0\text{ kJ}\cdot {\text{kg}}^{\text{-1}}$ and specific volume of $1.128{\text{ cm}}^{\text{3}}\cdot {\text{g}}^{\text{-1}}$ .

(b)

Interpretation Introduction

Interpretation:

To determine $\text{Δ}U$ and $\Delta H$ for the process when the water is brought to vapor state at $300°\text{C}$ and $1500\text{ kPa}$, where internal energy is $2784.4\text{ kJ}\cdot {\text{kg}}^{\text{-1}}$ and its specific volume is $169.7{\text{ cm}}^{\text{3}}\cdot {\text{g}}^{\text{-1}}$ .
