Chapter 6, Problem 6.32P

Interpretation Introduction

Interpretation:

The heat that must be transferred from steam to reach a temperature of $\text{200}\text{C}$

Concept introduction:

The heat transferred depends only on the internal energies of steam under the initial and final conditions and volume is kept constant according to the given process.

$\begin{array}{l}{\text{Q = m (U}}_{\text{2}}{\text{-U}}_{\text{1}}\text{)}\\ \text{where}\\ \text{Q = heat transferred}\\ \text{m = mass of steam }\\ {\text{U}}_{\text{2}}{\text{ and U}}_{\text{1}}\text{ are the final and inital state internal energies}\end{array}$
