Chapter 3.8, Problem 5E

(A)

Interpretation Introduction

Interpretation:

The water is boiling at a pressure of

Concept Introduction:

Thermodynamics property table.

(B)

Interpretation Introduction

Interpretation:

The initial and final cylinder volume.

Concept Introduction:

The relation between the volume $\left(V\right)$ and mass $\left(m\right)$.

$V=m\cdot \nu$

Here, specific volume is $\nu$.

(C)

Interpretation Introduction

Interpretation:

The work done $\left(W\right)$ in this process.

Concept Introduction:

Work done equation for constant pressure process.

$W=-P\left(V_{final}-V_{initial}\right)$

Here, constant pressure is P, initial and final volume is $V_{initial}$ and $V_{final}$ respectively.

(D)

Interpretation Introduction

Interpretation:

The change in internal energy of the water

Concept Introduction:

The change in internal energy equation.

$\Delta U=M\left({\widehat{U}}^V-{\widehat{U}}^L\right)$

Here, mass of water is $M$, specific internal energy in the vapor phase is ${\widehat{U}}^V$, and specific internal energy in the liquid phase is ${\widehat{U}}^L$.

(E)

Interpretation Introduction

Interpretation:

The heat added for this process

Concept Introduction:

The heat transfer equation for the process using internal energy.

$Q=M^V{\widehat{U}}^V+M^L{\widehat{U}}^L$
