Chapter 12, Problem 12.53QP

Interpretation Introduction

Interpretation:

The boiling point of water when external pressure is $\text{118}\text{mmHg}$ has to be mentioned referring to given datum.

Concept Introduction:

Boiling point of water refers to the temperature at which the vapor pressure of water equals the external pressure.

Vapor pressure is defined as the pressure exerted by the vapor phase of the liquid that is in equilibrium with the liquid phase.

The Antoine equation can be implemented to calculate boiling point of water at various range of external pressure values. The equation is follows –

$\begin{array}{l}{\text{log}}_{\text{10}}\text{P}\text{=}\text{A}\text{-}\frac{\text{B}}{\text{C}\text{+}\text{T}}\text{.}\\ \text{where}\text{P}\text{=}\text{vapor}\text{pressure}\\ \text{T}\text{=}\text{Temperature}\\ \text{A, B, C }\text{are }\text{constants}\end{array}$
