Chapter 3, Problem 3.73P

Interpretation Introduction

Interpretation:

The volume change of vaporization of ammonia at $\text{20°}\text{C}$should be estimated.

Concept Introduction:

Volume change of vaporization of ammonia is calculated using virial coefficients i.e. Reduced forms of pressure and temperature.

The reduced temperature and pressure can be calculated as follows:

  $T_r=\frac{T}{T_C}$

And,

  $P_r=\frac{P}{P_C}$

Here, $T_C$and $P_C$ is reduced temperature and pressure respectively.
