Chapter 12, Problem 100IAE

Interpretation Introduction

Interpretation:

The boiling point of water in Leadville, Colorado needs to be estimated.

Concept introduction:

The temperature at which the vapor pressure of a liquid is equal to the standard atmospheric pressure (1atm) is defined as normal boiling point.

Barometric formula: $P=P_0\times {10}^{\frac{-mgh}{2.303RT}}$

Here, m is mass, g is acceleration due to gravity, h is height, R is Universal gas constant, T is temperature.

Clausius Clapeyron equation: $\ln \left(\frac{P_2}{P_1}\right)=-\frac{{\Delta }_{vap}H}{R}\left(\frac{1}{T_2}-\frac{1}{T_1}\right)$

Here, $P_1$ is initial pressure, $P_2$ is final pressure, ${\Delta }_{vap}H$ is enthalpy of vaporization, $T_1$ is initial temperature and $T_2$ is final temperature.
