Chapter 7, Problem 143SAE

Interpretation Introduction

Interpretation:

From the given set of statements, the false statements needs to be determined.

Concept introduction:

The internal energy is represented as follows:

$\Delta U=q-P.\Delta V$

Heat transferred at constant volume process is denoted by q_v. Since $\Delta V=0$ at constant volume, $\Delta U=q_v$

Heat transferred at constant pressure process is denoted by q_p. Since volume can be changed at constant pressure, $\Delta U=q_p-P.\Delta V$.

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

Therefore, $\Delta H=q_p$
