Chapter 9, Problem 10QAP

Interpretation Introduction

Interpretation:

The temperature at which water boils in Glacier national park is to be calculated.

Concept introduction:

Clausius-Clapeyron equation is an expression that relates the vapor pressure of a liquid at two different temperatures with the enthalpy of vaporization of the liquid. The expression is given as:

$\ln \frac{P_2}{P_1}=\frac{\Delta H_{vap}}{R}\left[\frac{1}{T_1}-\frac{1}{T_2}\right]$

P₁ = vapor pressure at temperature T₁

P₂ = vapor pressure at temperature T₂

$\Delta H_{vap}$ = Enthalpy of vaporization of the liquid

R = Ideal gas constant = 8.314 J/Kmol
